If I get around to it, my plan is to start a forum and blog site for the local village. Personally, I'd have little to say in the forums/blogs themselves; my job would be webmaster, and that's about it. (I've recruited the mayor and some of the other players in town to contribute columns -- with the understanding that they'll be open to cricitism, too.)
What I've found is that several of the web hosting companies offer free blog and/or forum software. Since I woudn't need full services for this venture (no necessity to have a few hundred email addresses, for example), I'd probably choose one of the low-cost outfits.
