Angelas and Pauls links suck ass. The only thing they are good for, is for the bottom layer of a backlink network. Throw about 10,000 of these things at a web 2.0 page to help it get indexed. Throw another 10,000 of them at each of the other 10,000 links to help get them indexed. If you use profile links in this manner, they can be useful. Never point these kind of links at your money site. It is only a matter of time before Goog realizes what we're doing, then they'll deindex billions of profile links, and if they link to your money site you may get penalized. That's all I have to say about that.
