There is always alot of topics around here asking "what opening should I choose?" and the like. So here is something that I hope will help you: http://www.chesschitchat.com/opening/survey-of-chess-openings
I think it's a nice little site but it doesn't go into any sort of detail. It pretty much lists the openings without providing much info on the style of the game. Is that a site you created?
I also that something you want to add to the site is a reason for anyone to use the material. For example, who is the author of the site, what is his playing strength, tournament history, etc. I get suspicious when reading some of those articles..
It looks like a great start, I'm a little jealous because i wanted to start my own chess site. I'd say add some more details and yes, 1.c4 is missing which I could really use right now.
