Right, the market is full of point solutions that keep focusing in only one aspect of the communication problem. Sort of like UNIX command line tools: great at doing one thing, but loosely coupled with other apps you use.

Yammer is great at microblogging, falls short for the rest. Email is great for 1 to 1 messages. Campfire does chat really well. Asana or Trello do tasks. But your data still lives in a dozen places.

I started a company around the very problem you mention, trying to bring together all the tools I used, and we're now close to 250k business users. And, despite the big guns like Yammer, we're seeing our revenue double every 4 months. Take a look if you're curious, it's called Teambox (http://teambox.com) and it brings together tasks, GDocs, chat, wiki-like notes, etc.

Disclaimer, I work at Yammer.

I'm not going to plug our product's features here, but I'll say this: microblogging is not an accurate portrayal of what it is anymore, and hasn't been for at least one and a half years.

Care to elaborate on what it is? At work we looked at Yammer, some people use it and others don't. However, my impression awhile back was "great another facebook but for work". (I mean no offense to it, I am honestly interested in how you view yammer.)
