I have been using Entrecard for some time now. About 10% of the visitors come to my blog through Entrecard. Recently Entrecard launched a new service called Marketplace. Entrecard members can buy and sell their services in exchange of Entrecard credits.
I think this is a great idea. People can earn EC by offering their services to other community members.
Today I posted my ad on the marketplace. I just wanted to test how well this new option is received by the Entrecard community. I am offering 125 by 125 ad spot on my sidebar for 1 month. The cost is only 5000ec. Check out my ad.
Here is a promotional video to tell you more about the Entrecard program.
