What differentiates Slack from other similar products?
Slack makes communication fast Easy and transparent. I especially like how conversations are organized into channels, which makes it straightforward to collaborate with AEs, marketing, and ops without getting stuck in long email threads.
What is your favorite aspect of this product?
Very important Slack addresses slow fragmented communication across global teams by bringing conversations into a single shared workspace. Rather than relying on long email threads or getting stuck in time-zone delays, discussions happen in real time and stay easy to find and reference later.
What do you dislike most about this product?
There was only ever one time when I've had issues while sharing a file. The failure of an upload can happen for any number of reasons. I can appreciate that poor internet might be one of the causes of something going wrong. This isn't an absolute cause every time, though. An appropriate pop-up or chance for us, the end users, might allow us to have a better idea of what caused the problem in the first place.

Slack solves the problems Quickly of scattered communication across emails and multiple tools and it helps me by centralizing all globle team conversations making it easy for me to collaborate fast and effectively.
