About Slack

Slack is a cloud-based project collaboration and team interaction tool designed to facilitate communication across organizations. The solution caters to various industries, including media, research, technology, education, financial services, retail, transport, and logistics. Slack provides public channels for members across organizations to start conversations. Private channels enable interaction within smaller teams, and direct channels help send messages directly to colleagues. Slack incorporates feeds from social media into the application and blends them with ongoing conversations in various channels. Files such as PDFs, images, documents, and spreadsheets can be shared via drag and drop. Slack archives messages, notifications, files (as well as the contents of files) and projects, all of which can be searched for later. Slack allows users to customize their notifications and reduce their scope. All changes are reflected in the native applications available for iOS and Android.

Slack is the absolute best communication tool

I love Slack! I've used Slack for 5+ years, I've also integrated it into numerous companies I worked with. To me, it's the absolute best work comms platform.

Pros

Huddles! It's so great to be able to hop on a quick call, with or without video, to chat about a task briefly. It's a game-changer for remote workers.

Cons

I like the canvas options but it can be confusing.

I am a professional developer who has used Slack for around 5 years

I enjoy how Slack is in a unique space of being the preferred messaging platform for software developers, both enthusiasts and professionals. It is modern & feature-rich enough to fit both personal and professional use. As mentioned earlier, the adoption on the professional side lags behind similar tools. I’ll finish by saying one of the most versatile features that Slack for Enterprise has built is the workflows/automation feature.. and it should continue expanding on this feature to outpace it’s competition.

Pros

The interface and integration capabilities of Slack are several times more modern than similar messaging tools.

Cons

Slack has more work to do to overtake market share in Enterprise use cases, meaning those professional teams who are already integrated into the Microsoft environment and prefer Teams. It is often the case where Slack is used on the side, as an addendum, to a team that is already using a different communication platform. I guess this kind of problem would be best remedied by better marketing & outreach to promote Slack’s features and ease.

Slack for building a community

My overall experience with Slack is good. It is the best tool in the market to build a community and manage projects within.

Pros

I like that I can create private channels for me and my C-executives team and control who access the channel. I like that I can access Slack in different ways like Web based, Software and mobile application which enable me to stay up to date with my Slack community anytime, anywhere. Integrating third party apps like Calendly with Slack is also very useful for me.

Cons

It is really confusing to find the people and conversations where I was tagged or mentioned on Slack. Sometime Slack sent me notification on email which I prefer, and many times it does not. Also, I don't like video calls in Slack, the quality if poor and the feature for sharing my screen is not very functional.

Fun tool to stay connected with your team.

Overall, I'm a big a fan of Slack. I really enjoy being able to customize it to my needs, and keep conversations separate in their respective channels. I also like that I can add a guest user at no additional cost; this is great when I just need to extend access to one channel to someone. The software is super user friendly and the ability to customize the layout colors and emojis make it super fun!

Pros

Slack is an awesome team tool! I have used Slack for years now and absolutely love it. It's easy to create channels for different topics and select who has access to each channel. You can build lists, save items for later (bookmarking them), view activity at a glance, direct message other teams members, and even customize and add fun emojis to the platform. Our team has so much fun with the emojis throughout the day! It's actually the best part of our day because it keeps the conversations fun and engaging.

Cons

I have yet to find a way to upload custom backgrounds for the huddle calls. The backgrounds that are available as default in the system don't do well during live calls. The image is poor and it's not a great user experience there.

Slack is the internal chat tool for any business

Great piece of software that does what it sets out to do very well. We've tried Teams, Hipchat, RocketChat and Slack is by far the best.

Pros

We are a prodominently remote business now and what stands out most about Slack is its ability to centralize communication in a way that makes teamwork seamless. The channels allow for organized discussions around specific topics, and the integration with other tools makes it easy to streamline workflows. It makes collaboration feel more dynamic because you can react to messages, share updates in real-time, and even automate some tasks to save time.

Cons

One of the things I like least about Slack is the potential for information overload. With so many channels, threads, and messages, it can sometimes feel overwhelming to keep up with everything, especially if you're part of a large team or working on multiple projects at once. Notifications can pile up quickly, and it’s easy to miss important messages buried in a sea of conversations.

Alternatives Considered

Rocket.Chat

Reasons for Choosing Slack

Teams kept crashing all of our computers and was very clunky.

Reasons for Switching to Slack

Slack is a more established and supported product with lots of integrations
