Nice, well laid out. Great colour scheme,
good to see that you are keeping it relatively simple in terms of the number of categories.
I must say that I dont understand why you dont make the jump to 'Paid for' hosting from the very beginning so that you can get control of the advertising. If you sign up for google adsense it's bound to cover the cost of a hosting package.
Anyway I wish you luck with it, you're jumping into a very very crowded arena but if you can get the ball rolling you could do well. It's a great start.
