Have you discovered yammer doesn't do these things particularly well?<p>I hate to see yet another product become "a better twitter for ____." You'll get more press if you actually solve a real business problem in there.<p>How about making it integrate with ticketing systems, so that it's automatically updated? How about integrating with version control, so that commit messages share the story?<p>Obviously these things are developer focused, but these are the things that get missed in apps like this. Tell me what I'm doing, not the other way around. (obviously I should be able to talk too.)
