To call the conceptualizatiom of SMTs amazing would be the understatement of the year! It's going to be really really crazy if we don't have mass adoption in the future. A lot of businesses out there looking for incentives for their users; what better way to get this than SMTs! Imagine getting paid to browse through a site! Who wouldn't want that!?
Thankfully @ned and the guys are hard at work on this! So can't wait!
