Propeller.Com is a social networking site which I am growing to like a lot. The links it gives are relevant and very little spamming is evident at all.

The pages are set out nicely and the effect is one of good web design. From the point of view of SEO the backlink potential seems good, although as in all Web2 Social Bookmarking the main reason for visiting and posting the best pages you find is in the traffic which finds its way direct from the site, which I imagine is good.
