Slack is so bloated and annoying to use, unlike IM services back in the heyday.

So true. I used to have Trillian running on 3 or 4 networks, hardly taxing my late 90s computer. Every time I see Slack I get an urge to close the tab because I can almost feel the browser engine groaning in agony.

There's a Slack protocol plugin for Pidgin (and other libpurple clients).
