The theme is nice and simple.
I feel you can really improvise on the logo.
And it will look much better if you include this:
"Observing the Web.. With an apple macbook"
in the logo itself.
On the about page it should be:
"This blog was created on Christmas i.e. 25th. of December 2007."
As you scroll down the sidebar gets empty. You should utilize it. Maybe with tech trivia or something.
Chetan,It's a nice blog!
