Haha, Reddit has just announced that they will release Reddit notes (950K), randomly distributed among active members. I predicted something similar, that in a few years major retailers will release their own coins. They already exists as Xbox points, or Amazon rewards or whatever is that called.
The advantage over bitcoin are/were:
--random and more even distribution over a very wide userbase. This causes a kickstart, cutting down on 3 years of bitcoin history.
--bigger usability if the retailer doesn't let bitcoin to be used just the own coins.
Again, everything is the same as with bitcoin, except a large premined set of coins are distributed among millions of users and the retailer will favor its own coins over bitcoin, but they will let it be used for other retailers too. This gives more value to the coin.
It is basicly a secondary stock offering of some kind....
