Are you still into Entrecard? The blogging world survived without Entrecard before. There are memes that you can depend on if you want traffic or at least a change in your Alexa rating. Blog hopping is still the best and commenting on the blogs you visit even increases your Technorati links.
As of me, I have been dormant, I guess. But, I am still with Entrecard. It is still the easiest way for me to gain traffic.
