I had Smorty recommended to me by another web writer, and I just signed up for that. The site's layout seems similar to PayPerPost, and the posts pay similar amounts. What I recently found out about PPP is that Google is reducing everyone's page rank that uses them. I don't give a crap about page rank, but I know a lot of bloggers who do, so it's something to think about.
If you want to blog for money, Smorty seems like a safe choice. Google is not penalizing them and the projects look straightforward and simple to perform. If you're interested in blog advertising, Smorty can get your item and link on blogs in whatever categories you choose. And if you have a site to advertise, it isn't expensive to get started and pay bloggers to mention your site. So, with this site it's not hard to find opportunities to get paid for blogging or to advertise on blogs. Both can be done on Smorty.
