That's two very good points. I did not think of the image hosting aspect. That scenario would not be fun. And as for the 30 day payout. Yup, it also buts a drag on the sharing of content.

Ex. I had a follower re-steem one of my 30+ day old posts and it picked up a chunk of fresh upvotes, but since it doesn't pay anything he said he would only resteem less than 30 day content going forward. That's less sharing of my content now.
