Can't say I'm that impressed. "Anyone" can setup a blog or something, write a nice little article and get on front of digg, delicious etc.. If it was all from search engines, then I would be impressed :]
Hmm, I guess you're right. What if it continues? Haven't used Digg, Stumble or any such sites. 25% search engine. 5% word of mouth by visitors.
It's more like 21% word of mouth, which leaves the rest as 49%. The 49% basically comes from aggressive guerilla marketing and from top ranking pages in Search Engines for my terms. So I guess most is also search engine traffic. I will be trying some new things this coming week and will keep you guys posted.
