Dribbble is a really great site with really great people and the quality of content is excellent. Some of the best designers in the world use this, and it is inspirational.
If I had one criticism it would be that the "in-crowd" sort of dominates the site. It's not impossible to get noticed, but it is very difficult, if not impossible, to supersede the top "Players".
I am a member now, and will continue to be a member for the foreseeable future, and I recommend it to anyone.
I have ordered many, many books from Amazon, and have never had a problem with a product. Good sellers, good information, and easy-to-find search results.
The design of the site really needs to be updated though, and one time a book was actually not in stock when I ordered it, so I waited three weeks to find out it wasn't coming.
