I don't really get what purpose redditnotes serve? Are they IOUs with a fixed peg to the dollar or are they suppose to have their own market price?
If they are in some way supposed to represent "shares" in reddit, then I would imagine they would benefit from dividends and voting.
If redditnotes were implemented with BitShares UIA, then the proposal voting feature of UIA allows reddit to let redditnote holders vote on proposals affecting reddit.com. So that is one advantage our solution already has (or very soon will have) over others.
Dividends could be implemented by batch transfers of BitUSD to redditnote holders, but to be really useful it would be nice if that functionality was built into the code base (see the five posts starting here
). If we had such a feature it would make UIAs even more useful and provide another advantage of our system over other ones.
