BlogBurst From what I read on the site they pick blogs (you have to submit yours to them first) and let other sites choose from your blog’s posts to run as content on their sites. You get the linkback to your own blog/ original post. It is a way of building traffic. Might be interesting. I haven’t been making a lot of blabby posts lately.
The only things concerning me about it are having my content (written and photos) ‘borrowed’ without giving my permission. Also, I never like anything where the site or people decide whether or not to accept me. I just don’t like being judged.
