Web development, design, and site optimization

Today I came across a very interesting site/service/social networking platform called Entrecard.com. The concept is this, blog owners can swap ads (blog ads) with one another using a points system. You gain points by visiting other blogs that are within the Entrecard.com network. You also gain points by selling ad space on your site. The costs of either your ads that you sell or the ones you are trying to buy are all tied to a rating system that rates user activities in the system. The more you visit other blogs and the more ads you sell, the more points you earn to buy premium space on premium blogger sites and the more valuable your avaliable ad spots on your sites become.

I have been using it for just one day, not even a full day, and I have already noticed a considerable boost in traffic. I am still working on getting more people to comment and interact. :)
