I stumbled upon BlogChalking today. You can read about it at http://www.blogchalking.tk/

I signed up mainly just for fun. Here is mine:
This is my new blogchalk:
Canada, British Colombia, Victoria, Esquimalt, English, , Greg, Male, 26-30, Mountain Biking. 🙂

This seems like a great way of finding blogs like yours, or blogs made by people close to you. For example, this google search is for all the blogchalked blogs near me in Victoria that speak english.
