When the Slack sales team came to my employer they pitched it as some sort of memory store - the reality is that it’s nigh impossible to pick out a specific bit of information after a couple of months unless you remember who said something, where they said it, and approximately when. It’s also annoying when an admin leaves because only the owner can remove their account - not another admin. I would also say Slack has a very bad habit of forcing new features down users throats - people have been complaining about threads for years but there is STILL no way to mute them or disable them. Someone installs an add-in that makes a lot of noise? Tough cookies to you, your options are to put up with it or uninstall it, there is no way to mute it. Like people joining you to new channels? No way to stop that either. Their API is a pain to deal with in staticly typed languages - you often have to decode a member of a substructure to discover what the overall type is. So overall I would say it’s definitely not an e-mail replacement and it’s very heavy handed for IM, there is definitely room for another product. I would personally prefer something more akin to IRC or the classic “cb simulators”. The only real challenge today is working with mobile clients (and challenge is probably too strong a word).
