When I post I usually hang around in chat after a live post and then make any corrections that I didn't see in here.
Personally posting a post in meta first doesn't appeal to me that much, but I will happily take any corrections on content or grammar in comments, here, or in the Server Fault Comms chat room.
Just keep in mind if you take it the extent of http://english.stackexchange.com/questions/2153/should-kyle-be-corrected-and-if-he-doesnt-why I will just get confused :-P
