U recently added backlinks section on your right. This is because I use a free stat counter. This logs the people who visit and various info like how people get to my blog. Mostly it is through google searches for something. but today I discovered two new services..

blogsnow scans all the blogs in the world and categorises subjects. Making it easy to see who is bloging about whatever.
seems to offer a similar service but looks more cluttered that the blogsnow site.

anyway they are their for your delectation and delight
