A lot of people for some reasons think that entrecard is useless. While its half true, I think a lot of people just dont utilize it well. (full post here: http://www.melvinblog.com/2009/08/real-gold-entrecard/) Ok, forget getting traffic from it, but heck you can use it to: 1. Get tons of backlinks by sponsoring to a contest (major serp benefits) 2, Get a quality design for credits. 3. Actual Goods for credits 4. You can cash out the credits itself... What do you think?
