It's been about a month since I signed up for PayPerPost, and I've finally verified that it's legitimate:  I got paid $10 today for my first post.  Here's how it literally works: 

1.  You select a posting opportunity from the PPP website. 
2.  You write about it with the right number of words, include the proper links and/or pictures, and make sure you have the proper tone (that's the controversial part). 
3.  You wait about 3-4 days for your post to be approved or rejected (I haven't had any rejected yet). 
4.  After 30 days, the money ($2-$10 per post) is deposited into your PayPal account. 

Here are the terms and conditions for each post: 

All posts must remain up for at least 30 days.
You may post a maximum of 3 paid posts in any given day.
Paid posts may not be consecutive. Each paid post must be separated by at least one non-payperpost post.
All posts must be in English on an English Blog.
Your blog must be at least 90 days old with at least 20 pre-existing posts.
Your last regular post must have been within the past 7 days.
Content must be original. You may not post the same content on different blogs.

For me, it's a great way to make a few extra bucks to pay my webhosting costs.  It's certainly not enough to quit my day job, but it's nice to be able to make some money doing what I'd be doing for free anyway.  Some people at PPP have made upwards of $2000 over the course of several months.  I don't see that happening in my case.  And seeing that advertising still isn't making me any money, this is a great alternative.
