Criteo AutoRoll Widget, a new widget for blogs, is looking for beta testers. AutoRoll is the blog roll of your blog's readers. It’s a widget that displays links to blogs your readers are visiting the most often.
Criteo traces the number of visits of each unique reader on each blog that has installed AutoRoll. The more often a reader visits a specific blog, the greater his affinity is with your blog.
It takes one minute to install: http://widget.criteo.com/.
(NOTE: I am not getting paid to say this. I have not downloaded Criteo AutoRoll Widget myself. But Peter, the project manager at Criteo, sent a well-written e-mail that struck just the right tone of flattery and sales. He had read my blog. He didn't just copy my e-mail address. He took the time to do it right. These kinds of things need to be rewarded in this day and age!) ;)
