I wouldn't worry about it if I were you.
Try to enjoy browsing the forum and discussing topics with other members, rather than hoping to make a popular thread. I've only made a few threads throughout my time here, and most of them don't get more than 20 replies or so.
Nonetheless, the key to a good thread is keeping it brief, making sure it looks tidy, and discussing a topic/theory that hasn't been discussed a thousand times before. If you put a lot of research and effort into your threads, they're sure to get some attention.
Heh, looks like this thread is popular already. xD
