The template you've choosen looks pretty nice, but does it fit your blog's "theme"??
Since you're mostly writing about computer and online stuff then maybe you should try to find a more "technology" like theme instead?
It's also good that you haven't flooded your blog with useless widgets/gadgets and ads, but I don't think a few well placed (and integrated) Google ads would have hurt.
MAybe you could get some extra $$$ from them as well...
