Blogger (owned by Google) where you can do adsense and amazon.com
Xobba Tribune - premium site for adsense and especially amazon.com
Info Barrel - outstanding for adsense and Chitika (somewhat)...also uses amazon.com - but not so well.
Best Reviewer - adsense, but mostly useful for driving traffic to other sites.
Redgage - works totally differently from other sites, but is also useful for backlinks/driving traffic to this site, or others that you write on.
Excerptz - adsense and backlinking to other sites.
Those are all sites that I use personally.
