Does it Work?

Recently I have added a new element to my blogs. Its called 'Blogosphere' and you probably can see it to your right of this. The site that I got the code for this wonderfull little widget is Blogrush. This site claims it helps to bring traffic to your blog site. I thought it was worth a try. So far I am undecided. Why don't you give it a try. Check out some other blogs and give me some feed back and help me decide if it was worth it or not!
