Four Better Ways to Collaborate than Google Docs

I've tried Google Docs. And for small projects and small teams its OK. But it isn't fabulous - at least not yet. Lots of other Google stuff is really good, so I'm sure Docs will get better. But in the meantime, if you're looking for an online collaboration document tool, David Strom has a pretty good article. He mentions Etherpad, SlideShare, and Yammer and how you might use those instead of Google Docs.
