Positive: I think the color choice is very well done. I like the black, grey, and orange. It is dark, but not too dark for an overall site. I like the way the tutorials are layed out with a thumbnail picture. The navbar is also very easy to use.
Negative: I would agree that there are too many ads. Also the place that says ads on the left should adjust so there isn't all of that blank space. Other than the ads I have a couple other suggestions. I firstly think you should center the site. Along with centering the site you should center the white links at the bottom of the page. The other thing you can do is hire someone on NP to design a really good banner. With a better banner, less ads, and a centering I think this site could take off.
