- Is the idea interesting ? Yes possibly. The idea of making it easy to create tokens is interesting. I can see twitch streamers giving away tokens to their subscribers / viewers.

- Does it need to be on blockchain ? For all the use cases described, the answer according to me is no. It is easier to simply have a frontend through which users can interact vs maintaining a wallet, installing metamask, etc. This is going in the direction opposite of the Dropbox example - making things harder for users.
