Another great idea Jace...
Not exactly a review, but just my

added.
What I like from sponsor RSS feeds the most is options...
1. Allow me to choose whether I want nn/or more explicit picture content being pulled in.
2. Give me more than 3-4 sentences, and please for the love of God make sure that you have ran a spell check on your fucking feeds. I've had a couple that I've been in absolute love with, but having to correct constant obviously outsourced writer errors gets very fucking annoying.
3. Watch your keywords, and put a few categories together for me to pull from. I love getting a post from a sponsor, and its uncategorized from thier site. Is it to hard to add in a teen, hardcore, "model name"... etc category?
4. Models personal blogs, while great for outgoing links on my sidebars as friends sites... do absolutely nothing for me content wise. If you are going to do this style of blog, have some decent links back and some content.
