Slack Overview
What is Slack?

Slack is the top choice for teams to communicate. It provides a virtual workspace that helps teams maintain open communication in a business environment. With Slack, users can host voice and video calls with up to 15 participants and even screen share with a desktop app, empowering better user interaction. Slack also supports options for private and group sessions, and one of its best features is Slack Huddles–an informal meeting space that lets you directly talk to your channel where you can share screen side by side with your team. The platform integrates well with Dropbox, Google Drive, and Trello as well.

"The best collaboration and corporate communication platform."
What do you like best about Slack?

Slack is a comprehensive and solid platform for corporate communications and collaboration. We use it on a daily basis as our primary communication tool and it works pretty well. I like its intuitiveness, user friendliness and flexibility that makes it super easy to use. It has lot of integrations like Gmail, Google Drive, Confluence etc.

Slack can be overwhelming especially to new users. It requires some time to learn and understand its functionality.

I have been using Slack for more than a decade now and it has been of great help. The features that it offers are amazing, you can easily communicate with other colleagues by chat, video conferencing or call which is really amazing and incredible.

"Slack 2024: Navigating the Future of Workplace Communication"
What do you like best about Slack?

Slack provides a central platform for team messaging, where you can create specific channels for various projects or topics, making it easier to track conversations and stay organized. It also allows for direct messaging for private conversations, supports file sharing directly in the chat, and offers powerful search functionality to quickly find past messages and documents. Additionally, Slack integrates seamlessly with a wide range of other tools, such as project management apps and calendars, enhancing overall workflow efficiency.

What do you dislike about Slack?

While Slack enhances team communication, its high message volume can be overwhelming, and managing notifications effectively can be challenging, especially for larger teams considering the cost of paid plans.

What problems is Slack solving and how is that benefiting you?

Slack addresses the challenges of scattered team communication by centralizing chats, files, and project updates in one place, which streamlines collaboration and reduces reliance on emails, thus enhancing overall team efficiency and productivity.

"A well designed application for companies"
What do you like best about Slack?

I have been using Slack for almost 2 years now. Slack made company communications easier and also very FUN! It is very customizable, you can add as many channels as you want and you can modify it to allow certain people access to it, you can lock the channel or make it public, and you can also edit it post-creation. Dead channel? No problem, you can archive it and it would still be viewable in case you hold some dear memories in that channel so it won't ever be deleted unless you want to do so. You can integrate "Apps" or as we call them "Bots" on Slack for Examble, you can integrate Coda as a bot which can make any Coda link sent in Slack viewable or "Previewable" before you click. In my company, we integrated ChatGPT and gave it access to our customer service tools so when you ask it any question, it will respond appropriately to the company's rules! We also have a Confluence integration, which notifies us if there are any updated pages or newly made pages which is extremely helpful in a customer service job. Slack is used by us every day, it is our only method of communication between us and managers during a shift which makes everything said by anyone "Documentable" which is very nice. Slack outdid themselves on the last update, they made it look really nice and almost like what Discord looks which is nice.

What do you dislike about Slack?

For 2 years, I haven't seen any issues using Slack or anything that I dislike to be honest.

What problems is Slack solving and how is that benefiting you?

It solves the issue of contacting higher-ups as they can be viewed and contacted on Slack. Also, it benefits us by enabling us to document every step we make during work so that word of mouth is no longer a problem!

"The easiest, fastest way to connect with colleagues and get answers!"
What do you like best about Slack?

It's much quicker and easier than email. I'm able to share information with individuals and teams, ask questions to large groups, and gain insights that inspire cross-collaboration.

What do you dislike about Slack?

Sometimes it's difficult to find what I am looking for in the search.

What problems is Slack solving and how is that benefiting you?

With our entire company spread across the globe in 12 countries, it is the one unifier for us. It helps create a melting pot that drives community. In addition, as a content writer, just scrolling the channels gives me ideas for content I would not otherwise have. Sometimes someone will post a question about our capabilities and someone else will respond with an answer and an example that I was previously unaware of — so it helps to break down silos.

"Slack- The best corporate communication tool"
What do you like best about Slack?

Slack transforms team communication like never before! Our workflow has been completely revolutionised by its flexible capabilities and easy-to-use interface. Sending a message to coordinate cross-functional testing is now as easy as integrating Lambdatest with Slack. Our development process has changed significantly as a result of Lambdatest's interface with Slack, enabling more efficient communication and quicker problem-solving. Because the integration is so simple, we never needed customer support. We use it on a daily basis as a primary medium of communication.

What do you dislike about Slack?

Slack can be resource-intensive sometimes, particularly for devices with limited RAM or slower internet connections, leading to performance issues. Also, if I had to select a complaint, there are moments when you get too many notifications, especially if you're using several channels. Sometimes it feels like a bustling swarm!

What problems is Slack solving and how is that benefiting you?

When it comes to disorganised communication, Slack is a lifesaver. We can communicate, share files, and keep everyone updated without getting bogged down in never-ending email conversations because to this central portal. It has simplified our conversations, removed knowledge gaps, and made working together easy. For remote teams like ours, it's also a lifeline because it keeps everyone in communication wherever they are. We connect with our overseas teams using their video conferencing, which provides us a seamless communication.

"Go to tool for any messages"
What do you like best about Slack?

Multiple things, to name a few, Formating the message, the icon library, creating various groups, and moving groups under a specific group, starting a thread. It's super easy to have all things under my control.

What do you dislike about Slack?

It's hard to search direct chat groups created with a few of my peers a while ago. Just like how we get to know while using Whatsapp, which other groups two people were part of, it would be great to see such a feature, which may reduce the cognitive load on many users.

What problems is Slack solving and how is that benefiting you?

It gives me a platform to async between my team members. It saves a ton of time without jumping on to random zoom calls and communicating what efficiently matters the most.

N/A - I have had a great experience with Slack.

"Slack is pretty much the chat software that everyone should use."
What do you like best about Slack?

Slack has been designed very well. You can easily use the service without that much of hassle. It has been developed to be implemented in any type of business. You will get use to it very easy since you might be able to use it every single day. The features that the service offers are great, you can easily communicate with others by chat, call or videoconferencing which is amazing and the integration it has with other services or tools are great. I haven't had the chance to use their customer support since it has never failed at any point for me, ut I'm pretty sure their support is also amazing.

What do you dislike about Slack?

I woul say there is something less helpful since everyone uses it depending on their needs, for example, I don't find helpful the Threads section since I can go directly to the chat I have opened and that's it, but someone else might find that option very helpful bu I don't use it. The rest it's great. Everything works perfectly fine and you can get what you need in front of you.

What problems is Slack solving and how is that benefiting you?

The communication is always important and even though Slack is not the only videoconferencing service I use; is the one that I use the most and I'm comfortable with it. We can interach with others by chat and if we need to share our screen we just switch to a videoconferencing or to a call, so it's very versatile.

"Slack is my favorite team collaboration software and community platform."
What do you like best about Slack?

The organization of different threads. I've been able to join and build cool communities with this feature.

What do you dislike about Slack?

Sometimes, inviting people can be a little complicated. I had my rooms reset or something where no one could join unless they were with my organization, and links expiring, even though I've never encountered the problem previously.

What problems is Slack solving and how is that benefiting you?

I mainly use it for communities, but I also use it for one-on-one communication with clients.
