I find it quite easy to maintain communication on Slack since everything is neatly organized. The use of channels allows one to separate different discussions depending on what they are about, while direct messaging is more convenient to use when there is a need for instant communication. It is also convenient to use it because one can easily send files and search past discussions. Review collected by and hosted on G2.com.
At times, I have found Slack overwhelming due to too many channels and many notifications. Essential messages tend to be lost amidst all the chatter, making it difficult to trace them quickly. Another issue that I see with Slack is that it may take time to figure out how to manage notifications and organize channels for a new user. Review collected by and hosted on G2.com.
