I think it's good when the link is related to what people on the forum are actually interested in. Relevance is the name of the game no?
It is a source of generating traffic for your website. And also gives the backlink. so the signature link is very important part of the forums.

Thanks For Post Your power of forum signature links Article
I realized that mostly standard high PR forums do not show that signature, and it always depend on quality of forums. and i have seen many time some user use forum only for signature they don't have mean that what they are posting.
