I must be in the minority (based on the comments that I have read), but I hate it.
The other day the PHB announces to the office: We are going to use Slack and move away from IM, Skype, etc.
So I signed up.
What I don't like:
-you need to keep a a tab open all the time,
-you need to keep an eye on that tab in case something comes up,
-the 'notifications' don't work all the time (Archlinux + Firefox)
It's like somebody took all the bad qualities of IRC, and shoehorned it into a web-page and all the horror that brings.
The features that I don't understand:
search-able logging of messages. Email and/or Pidgin already does that.
Group messages: Email already does that.
Transferring of files: Email and/or corporate LAN shares already do that.
But it does add the necessity of stopping my workflow every 5-10 minutes so I can check to see if there are any messages that _might_ apply to me.
The quicker it can be killed with fire the happier I will be. Or am I missing the point?
curmudgeonly - check
beard - check
Unix admin - check
Perhaps there is no hope for me. Next thing you know people will want to take pictures with their cellphones! =)
