Qumana.com is a website that offers "tools for bloggers". From what I found, it mainly seems to be an ad program that you can implement on your blog. The site is extremely well designed and very eye catching. They seem to have a good reputation and i've read that they have great customer service. I currently use adsense for my own blog, but if I had known Qumana was around when I started my blog, I would've probably used this service because i like the fact that they aren't as big as google and customers say that they give "every customer the attention they deserve." One con however...Qumana seems to only work with TypePad blogs.
