This part:

Why are we limiting people here to having to create? Shouldn't they be able to be rewarded for interacting in the same way as they do now on other sites? Now that would take off!!!

is brilliant.

Assuming the account creation limits were fixed and people were able to actually make some STEEM for doing the normal social media things, then we'd have a huge pool of potential readers.

The bigger the pool of readers, the more chances the real content creators have for getting upvotes.
