I don't have experience with most of these sites, so the info below is me "reporting" what I found online and not first hand experience. Right now, I'm doing some research and thought I'd add it here.

As I find out more info, I'll update this thread. If you have something to offer, please add it too.

If you're going to post articles on other sites, then we should look for a variety of benefits when chosing which articles to post to, such as:

authority/PR
ability to pass link juice
revenue share
possible search engine rankings for the article itself
revenue sharing
Internal traffic possible - Can the site drive traffic to your article directly due to populartity of the site?

These are all factors and the two sites that come to mind that fit all 5 criteria are Squidoo and Hubpages.

Here's some details:
