I used to do that. But it doesn't work nearly as well when there's a good group of solid and habitual editors out there - there were times where someone else would find the same error and fix it before I got there 'later'.

But for the original poster (OP) -- Start small, and watch the Wiki Activity page to see what kinds of edits others are doing. You'll get a feel for the style we're looking for and the kinds of changes that we make, too. Of course, if there's something in someone's Sandbox or Blog post, don't touch that - they're experimenting.
