This site is all about tutorials, I have written a lot and a lot more submitted by other sites and update it almost daily now. This site is programmed 100% by me almost all automated now. I want to know what is missing in the site specially for design. Also, about the ads placement and SEO. Thank you very much in advance.
The suggestion I give you is to add a feed rss for each one of your section.
In that way your visitor will be able to enrole to your web site and they will come back each time you will publish resources that match their interests.
Good website loads pretty fast, but to many empty spaces above the search box, below friends category and on the right side of the page you could fill these with google adsense.
