I like this NYTimes article on becoming more productive with wikis, etc.:
We need a new term to describe “hosted collaboration application with a wiki” because that’s a lot to type each time. How about collabappiki? Better yet, how about collabapp?
If your job requires you to interact with co-workers and track what happens, you’ll be using more collabapps in the future. The more you collabapp, the less you e-mail.
Would that everyone wanted to collabapp! It does require a different mindset, that’s for sure.
