> Its a safe social network. I'd much rather post memes in Slack than on Facebook or Twitter

Facebook has private groups, too. (I assume Twitter has something similar.) At worst, this is a great demonstration that defaults matter. I often hear people speak as though Facebook/Twitter/Slack/IRC/etc are only usable in their default mode, even though most people I know don't actually use them that way.

> Slack also almost never falls down. Its remarkably fast

I feel like the chat software I used to use called "Slack" was completely different than what I hear other people talk about by that name.
