My good friend David Peralty has put up a great, and frank, review of Entrecard and why he won’t be using the service.
Essentially, Entrecard is a service that allows bloggers to swap 125×125 banner ads with other bloggers, free advertising if you will. It seems very similar to BlogRush, only substituting the syndicated post titles for graphics.
David hits the nail on the head when he says there are very few benefits. The banners aren’t indexable by so you won’t see any SEO benefits and because they rely on both Javascript AND Images, you lose a large chunk of your audience including blind people and users on a mobile, or any other non-javascript, platform.
