I have been an advocate for keeping potential $ rewards displayed on active posts as a marketing tool for a long time but I have been recently coming to the idea that it may be more detrimental than beneficial, as others have said before.
The UI of Condenser needs to do a better job of conveying a post's potential payout as something less solid, more ephemeral, less belonging to the user before it's actually paid out.
The way it is and has been since almost the beginning has contributed to user confusion.
Steem's killer app, or sweetest honey to attract more users, is obviously the post rewards. But at this point I think user growth from word of mouth is much bigger than someone stumbling here and seeing $ values on active posts.
