I don't get some people. They like to post in threads for the sake of posting, rather than providing useful comments. When it is in casual or news threads, no problem. It's your opinion and that's what a forum is all about. But when someone asks a legitimate question and it's a thread asking for some real advice, these people post their opinions anyways even if it's not true and totally not helpful. No one cares about what you think on situations like these. Just be quiet and stop losing the little credibility you already have.
