Does anyone know what Spark People is?

It has come up in articles several times in the past week.

http://www.sparkpeople.com/

I think it is a free website that is all about diet, exercise and health. I love the idea of having an online support community. I popped over to the site and they had several things that looked super interesting.

But...ya know what? I was only on for a few minutes and was absolutely BOMBARDED by ads. If you are going to offer a free site/blog, I understand the motivation to put the ads in but honestly, I would rather pay a few dollars and actually be able to read an article without three different pop up ads.

I am very interested in the site if anyone is using it, or had a better experience, let me know.
