Ayman
Best collaboration tool to use between your teams
Comments: Before being compelled to work from home in a distributed and asynchronous environment, I didn't fully appreciate the quality of Slack. However, when faced with the challenge of working remotely (and juggling kids' schooling from home), Slack has proven to be a valuable upgrade from traditional emails and other online collaborative tools. With Slack, I have access to a one-stop-shop that allows me to receive notifications for Google Doc edits and respond to them directly from the platform, saving me a significant amount of time.
Pros:
Slack offers a straightforward and effective interface for inter-team communication, elevating communication beyond emails and Facebook messages through a secure platform that caters to teams. Among Slack's standout features are its channel setup, which enables the creation of focused spaces centered on specific topics, and the ability to reply to individual messages within a thread. Channels help maintain my team's focus and keep them on track, while also providing a casual space for informal conversations (via our "Random" channel). Meanwhile, threads help prevent channels from becoming an overwhelming, jumbled mess. Additionally, Slack's ability to react to messages with emojis, share messages with specific individuals, create private or public channels, and send group messages to team members creates an environment that encourages collaboration and communication in a way that feels organic and intuitive. In summary, Slack's platform provides an uncomplicated, natural space for teams to work together and communicate effectively, replacing traditional text threads, Facebook messages, and emails.
Cons:
While Slack provides a centralized tool for online collaborative work, the learning curve can be somewhat challenging due to the non-intuitive nature of shortcuts and integrations. Additionally, subscribing to multiple Slack channels can be overwhelming and result in an excess of notifications that may prove distracting. However, this is the trade-off of having a singular platform for all collaborative work.

Streamlining Communication
Comments: While I appreciate the ability to create multiple channels in Slack, one thing I found challenging was managing them once I had too many. Specifically, as the number of channels increased, it became difficult to keep track of which ones required my immediate attention and which ones were less urgent. This meant that I had to create different notification settings for each channel, which could be time-consuming and sometimes led to me missing important messages. Additionally, managing and organizing my channels could be a bit cumbersome, as there was no easy way to group related channels together. Overall, while I appreciated the flexibility that Slack provided in terms of creating channels, I found that managing them could become burdensome as their number grew.
Pros:
One of the things I liked most about Slack is its ability to facilitate organized and efficient communication by allowing users to easily establish multiple channels within a single workspace. These channels can be created based on specific topics, projects, or teams, and users can join or leave them as needed. This not only helps to prevent information overload and keeps conversations on track, but it also enables users to quickly find and reference past discussions. Additionally, Slack's search function makes it easy to locate specific messages or files within channels, further streamlining communication and boosting productivity.
Cons:

Not bad for small groups, horrible for large groups, free plan is now crippled
Comments: Only using Slack with external teams that use them. We no longer use it with our internal teams. Their confusing threaded views is really their downfall. There are other alternatives out there that do a much better job.
Pros:
Slack has a very nice, slick interface. When the workspace is not busy, it's very easy to see all the messages and figure out what's relevant for you. Very easy to setup new workspaces and channels. And basically, the key reason why we use Slack is because almost everyone is using it.
Cons:
Their free plan is now crippled. Only 90 days of retention. On a number of free workspaces, I wanted to refer back to some info which I no longer can find. Very frustrating. Slack also implements threaded conversations as a "tack-on" feature. Not everyone uses this feature and it just causes more and more user confusion, especially in large workspaces where many messages are mixed into the main channel as well as in threads. Their threads/mentions&reactions views which are supposed to help you filter out things not relevant for you are huge messes. Their pricing plans are also very expensive.

A must for every business
Comments: Emails really become a thing of the past after a business adopts Slack as a communication channel. The possibility to integrate with many other tools also boost productivity in the workplace.

Slack revolutionised the way companies do business and the way employees interact with each other. It's an essential tool for every company, especially for companies implementing hybrid or remote working. It encourages friendly and daily interactions between colleagues and fosters a truly collaborative environment.
Cons:
Sometimes there are some minor bugs, like notification not working on your phone when you're part of multiple slack workspaces, but nothing that really spoils the experience.
