I'm thinking of starting a health-related blog together with my wife, and this has me thinking about bloggish matters. I'm wondering if anybody's every played an RPG online by blog. You could make each scene a new post, and then hash things out in the comments section, then update the original post and start a new one.
More exotically, you could play a Lexicon-like game, using the blog metaphor instead of the encyclopedia metaphor, and using linear time instead of the letters of the alphabet to move things forward. Agree on a common premise for the blog, say that it's the development blog for a cyberpunk software firm, or that it's the blog for a political journal covering the week that the Glorious Revolution started, and just keep moving forward, commenting and building off of each other's posts. It might have a bit more of an RPG feeling to it, if each player takes on the persona of a fictional blogger.
This could be very cool, or it could be just a communal way to create bad gaming fiction. I'd like to try it sometime.
