The best solution would be for the posts to be in a wiki, with two versions (a working version, and a public version approved by the author or authorized users) to keep vandalism from the front page, but with editing allowed to all users. This way, both typos and formatting issues could be resolved without bothering the author or anyone else (remember the encoding bugs in OB-imported posts, that nobody bothers to fix even after they are reported, not for a long time anyway!). Not a viable short-term solution, obviously, but technology will probably get there in a few years.
