Also don't wait for some one to post on your thread! Take the initiative and go looking for trades. If you see something you like on some one's thread post on thier's.
Something that I noticed is that most of your posts are you offering high end stuff for trade. Most of the collectors here are not going to be looking for that kind of thing. We have a LOT of midlevel traders here, and honestly most people cannot afford those types of cards (Babe Ruth bat for example). It's great that you have those cards, but try offering something a little more reasonable and you'll probably get more bites.
Also - I noticed that you have been offering cards for sale. You cannot sell yet, so please stop doing that.
