If the internets didn't have Google, I'd agree. But you want to force-edit people's posts, to make the boards potentially more understandable to hypothetical newbies that may or may not have basic reading comprehension skills necessary to interpret context AND for whom asking what the **** does X mean is too much effort.
So, sorry old boy, but I don't like it. There are better things to add to the boards, such as flash/YouTubes embed support in posts, a spellchecker, class-level dependent titles that work, PS3 gamertags, user blogs, etc. And if it ends up being added, it should be toggleable, to minimize possible inconvenience.
