I just read this from @anyx Thoughts @htooms ?

All comments are paid out 7 days after creation and there is no longer a second payout window.
I don't quite like the 7 days for the reward. It's simply too long for the average user to understand what is happening: People have short attention spans, and the volatility of reward is incredibly confusing to new users (Post valuation changing over time -- although one remedy to this solution is to only show users received RSHARES, and not the value in dollars. This would be a huge flip in UI and marketing however, as people are currently used to seeing $$$ values.). However, it is also incredibly hard to reconcile the "ability for old posts to go viral and recieve engagement", as I just mentioned, as well as the original post being rewarded. From a consensus point of view, there is no way to be able to continuously vote on content (this would balloon the amount of data to keep track of, forever). We need to think of a better way to, a) reward users promptly, and b) reward users for old posts that either get refined or go viral. Consider the welcome guide to Steemit: further rewards to the writer would be nice, as would the ability to modify and edit as steemit changes, and finally comment on the post like any other blog post. However, it is hard to reconcile a) and b) together, and I unfortunately do not have a solution.
