I think some of it is "worse than what": we were on HipChat, and it was not very nice, but at least they made an actual OS X application and allowed one to customize its behavior on my machine. The Slack "app" is just a packaged version of WebKit and has almost zero customizations. Worse of which is that there isn't a per-channel setting to hide images by default, since I've had no luck getting folks to stop posting animated gifs into the general channel. I'm not at work right now in order to speak to the specifics, but the Slack app doesn't handle that situation correctly at all.

And the notification is merely a red dot. Oh, you only want the red dot if you're at-mentioned or someone posts in your team's channel? Too bad.

If you just distribute your site's webpage as an app, you're phoning it in. And that is why I want a chat company to use XMPP so that I can use Adium to manage my interaction (or lack of it) with the chat service.

I'm glad you like Slack. I'm sure they're going to do well, given how many folks sing their praises.
