This is a great addition to the discussion of SMT that seems to be blowing up! You have me thinking about ideas for restarting former communities that were killed by Facebook and other social media sites, this idea could help bring like minded people, or people with similar interested back into a local-like community. I remember when forums for specific topics were huge and were the place to be. Do you think that SMT's could revive that culture?
:) since itll be some kinda API any app owners can use to integrate as part of their UI/UX, why not?
