I had a quick look, and here's my hopefully constructive criticism.
It's not clear who the website's target audience is. Is it aimed at nerds (who would probably know all the stuff that's written in the How To/Windows/Mac/Linux sections already) or non-nerds? Or maybe it's a site for trainee nerds
Might be useful to think about this.
I see you have a large advert to find volunteers for your game testing - so is this site a blog or an advert? No reason why you can't combine both, but I got the impression that the blog was just a cover for the advert, and if that's more important you could put the advert first.
Other than that, good site, well laid out, interesting with useful links.
