I'm most interested to see which one of these are most successful out the gate. I'm assuming distributing the tokens within the communities based on steempower will definitely be the most popular way at first.

However, I can see ICO's becoming the "BIG" thing once people in the steemit community figure out how to implement an ICO. I think this will eventually become the most popular/succesful method, but this way is also the steepest learning curve on how to implement it succesfully and replicate the way others handle succesful ICOs.
