Its not bad if you do it once in a while, I think I've probably done it too. But when you do it all the time, or post in topics that havnt been replyed to in a while, it gets annoying. Plus if everyone here were to reply with "lol"'s then it gets really hard to find what you are looking for through all the garbage posts. Plus, I for one, dont have all day to sit here reading topics that people bring back just to make some stupid comment. It takes me long enough as it is to get through all these, and if I were to reply to all these dumb comments, id be here all day. So it just makes it easier for other people basically.
