Actually - without sounding arrogant forget what was said in the previous threads.
Directories don't give you any traffic - link exchanges don't give you any traffic. I'll give you 3 sites that I guarantee will give you traffic, and if they don't I'll run around nakid shouting "I love V7N"
www.blogsearchengine.com
www.technorati.com
www.blogsearch.google.com
These three sites alone count for 30% of my traffic - the rest comes from Google, Yahoo and MSN.
