Forums & Blogs: The Game

[The Lizard of Oz]

A silly thought popped into my head a few days ago and I'm curious if anyone has tried this. Make a RPG, something smallish probably would be best, Holmes-style, using nothing but posts from forums and blogs. There has been more than enough things shared to cover races and classes, spells and magic, rules for combat and noncombat situations. I know have have used things I have read in some of the games I have played in, shields shall be splintered anyone?, but never tried making a full game from them. Could probably come up with a fun, if not goofy, little game. So, anyone tried something like that?
