It's good to see a website with valid markup, but the CSS validator came up with
one errorThe load time of the website was quite fast, as expected when yours is a website that doesn't (thank heavens) use an inundation of images.
Design wise it's okay, it's good that the website has a fluid layout and expands to the size of the browser ... It could be a little better organised though, in particular that bulky navigation bar at the top (which is repeated below ... although I think just text links at the bottom would suffice). The gap between the categories in the main section of your page is a bit large, and those ads, as always, irk me. Make them disappear ... and if you can't do that put them where they don't distract the user.
The colour scheme is pretty horrid, that bright blue is very painful on the eyes (and these are young ones, imagine the reaction of some 70 year old woman trying out the internet for the first time ...

) and that dark blue is a very generic colour ... maybe a blue with a bit more yellow in it would be better, and perhaps a very light grey to replace that cyan ... and get that yucky snot-like green off the screen before someone has a heart attack ... but ultimately it's your choice ... don't forget to choose colours that compliment each other, and that
includes the background!
You might want to include some pictures too, and not just icons and fancy text ... people will lose interest quickly without pictures or a good design, and your website has neither.
As to the content, at first I didn't know what the site was about because I couldn't see the relevance between the name of the website and its content ... it confuses me slightly.
Another thing I should mention is the relevance of the site as a whole. There are quite literally thousands of other website offering the exact same thing in the exact same way, and many have better designs. What is it that makes your website any different?
Thank you for your detailed review.
I have implemented your suggestions.
- reduced the gap between the categories in the main page.
I will try to add relevant images and also try to make the content more easy to understand.
and suggest more improvements.
