There is a new and extremely powerful widget in town, the Entrecard. Entrecard can most clearly be described as a business card exchange. What happens is you sign up for Entrecard and then drop your Entrecard ‘business card’ onto someone else widget on their site. It is a very cool and extremely great way to reciprocate and get cross advertising. Each person gets points for dropping off cards. You can then use your points to buy advertising spots on the other user’s sites. Entrecard is a great idea!
