Using social media - twitter to increase your website/blog traffic

Hi all,I just add one small tool in my 100k2 blog. It is the Twitter Follow Me Button.I put it at the right hand column of my 100k2 blog, I guess you can see it very clear. Checking back my twitter - http://twitter.com/100k2. I found out more people follow my tweet.Other than that, checking back Google Analytics, I found out some traffic comes from tweeter.
