I think a lot of it comes from the inflated rhetoric they present themselves with. It's a chat application, it's not curing cancer.

So your mobile notifications work without fail? On Android I receive one out of 20 notifications. The desktop app is horribly laggy -- and my computer can handle a lot. I have 2x 75Mbps internet links that stream 1080p effortlessly so it's not my net either.

And you're pleased with the lack of granularity of the notification settings, too?

Just try this out on linux (maybe works on other OSs): open a system manager with a real time CPU usage chart. Open the Slack desktop app (or a session in Chrome, it's the same). Open a channel (#random should work). Scroll up. Watch usage of all your CPU cores skyrocket. Stop scrolling. CPU usage goes back down.

They to hog all of my cores just to scroll up a list of messages.

BTW, this doesn't happen in Firefox: scrolling up doesn't cause CPU usage to go up measurably

Android app is a total disaster. Unreads? No you can't see them!
