Review me got a new feature that is so called 'product line', so what does this mean? this means simply beside traditionally reviewing you can post ads on your blog what the advertiser provide you. So you only have to cut and paste the content what the company has written this means that the company or better yet the advertiser has the total controle over the commercial content.
This takes a lot of work out bloggers hands. I think the readers can get bored when they read the same post over and over. I do not know about how the payments are I can imagine http://www.reviewme.com/ will offer less money for copy and pasting than a traditional blog post.
