I don't really think it makes any difference on the draining of the rewards pool. In the long run - I think it makes the network better/stronger as it encourages even more so the creation of quality content...because the voting window doesn't expiry. With this type of regard to content creation it's about sharing thing's that are simply to share...and it gives everyone a chance to see it and it's not soo much about getting as many views in 7 days as possible.
I think it would be cool to have a hybrid model of sorts with the voting...where a post is paid out like it is now after 7 days - and then it's just like once a month or something like that....like a passive royalty.
Sure worth a try ,hope it gets established and we get to see the good results ;)
