Woo Yay new App funz… but wait this is just likes/+1’s filtered by your friends right? So unless your friends are using it you have no point of reference. Sure you can Stamp stuff you think is awesome (like) but what about the new things you don’t own/haven’t been to?
You have no clue what to do, which means you have to sit at home or wander around aimlessly and stare at a blank (albeit well designed) UI ***cough*** Color ***cough** or you could just use the iPhone in your hands and well, call your friends and ask their opinion…
It’ll be interesting to see how this evolves and whether it overtakes Oink which seems to be the same thing but with more features and not quite as refined UI. There was a lot of hype for Oink (and I presume there will be for Stamped) and I’ve seen some usage in my Twitter feed but I’ve yet to be convinced.
