Links are the only think that will effect your PR, so please take no notice of numpties like above who clearly have no clue what they are talking about.
As for your earlier comment about the threads here, they do rank on google, in fact some of them rank rather well, so I'm not sure where you got that from lol
For the PR question, it will be because of the site structure and that most threads get a good amount of time on the forum main page in that top featured box area, which will likely help pass down PR.
Plus with good threads people will share the links on here, facebook, twitter and other social sites so that's more sources for them to gain rankings and a little extra toolbar PR from time to time.
Also, you might notice that some threads such as forums rules will be linked in some of our sigs, that will also be helping to pass PR around.
Well very great thought and very true. Thank you very much. I just gathered some bit of knowledge out of your reply.
