Any post that simply says "Me too", "Bump", "Up" or any variation thereof is Considered Harmful and should be flagged so that it can be dealt with using extreme prejudice. It is not "good form" nor is it useful.
If you can add information to the question, then an edit will earn it a bump but you should only do this if you really have something to contribute.
Alternatively setting a bounty will earn it a revisit to the front page as well as get it onto the featured page where one of our resident bounty hunters may kill it good and proper.
