The web is links. How those are done, and for what purpose, is what we all try to understand. If you wish to be unique, then do that! If you wish to be a content provider for other sites with no expectation of return links, then do that!
If they link back to you, as thanks, then they did that.
Short and sweet: Do your stuff. If you share it, don't complain if it hurts you. (Aside: I don't give stuff away, but I do demand a link if borrowed and I don't hit 'em with a take down)
Curmudgeonly old webmaster. Probably didn't read it right anyway. I thought you said I want to do a blog they can rip, give us links, but not be part of our site, yet we want the link juice... Did I miss the point?
