Slack isn't perfect; I agree with that. I haven't experienced the CPU issue, but it does seem to like RAM quite a bit. I just opened it w/ one account active, and it was eating maybe 400MB of RAM. I bumped that up to 6 open accounts, and now it's chewing up maybe 2GB of RAM.

I'm quite fond of emacs-slack, which is a much better client experience than the Slack 'web' UI.
