Please make a look at my site - hallowdemon.com

[hallowdemon]

Hi all,
Finally i have setup a basic site of my own, hosted on IMW.
URL: http://www.hallowdemon.com
hallowdemon.com is initially meant for publishing technical articles. but it aggregates some top news contents from other sites. hallowdemon.com also contain a discussion forum which allow users to discuss technical as well as non technical topics. Now the basic setup of hallowdemon.com is over. But i know there are lots of optimizations required. I am trying to reduce the data base access on each request. I am also in search of good articles to publish in it.
I request you to review my site and give suggestions for improving it.
Thanks,
Jitto P.Jose
