wikis

I cannot wait to get my hands dirty playing with a wiki. I have been toying around with the idea of creating a blog about my experience with local things. (This would "force" me to get out and explore). A blog would have worked fine. But,a wiki would be so much better. I would be able to organize topics better, restaurants, stores, nature, special events etc. I would also be able to edit the pages long after they are posted. The only thing stopping is finding a free wiki that would work.
