The only thing that stood out was the text for the title in the top left corner. It is hard to read I think you might be applying a drop shadow of white to it? Its hard to tell maybe darken up the drop shadow so the words can easily be read. One other thing was if you don't need an account to register then you could remove the widget on the side on the front page and put it under the More Page. Why I say the more page was becuase it was the first link I clicked when first visiting your website. This way it opens up that front widget so you could put more usefull things in it like top posters or most recent post excerpt. Something different with your own twist than the login. It loaded very fast which is a plus, I'm on a dsl connection. These are just suggestions I hope they help.
The overlaping of frames (themes) in the middle is not very inviting, where should one click? Take the adsense ads to the sitebar, do you want the visitors to click away from your site directly?
Hi, viewed your blog. It is Ok. But not impressed much. Visited the tech blog also . That is nice. Good information about new gadgets.
This is a pretty decent design. I agree with the others that your logo needs to be changed. It's super hard to read.
This is among the very few websites I have come across, which has the layout in blue and it looks neat as well. The site looks very well organised with good readability according to me. Only point is, there nothing much there to be read
