RE: OCD Sportstalk Incubation Curation Update
If you think about the rewards in terms of half of them coming out in hivepower that over time grows and gives you more and more influence, APY and many other benefits in the future (such as airdrops, account creation, possible smart contracts requiring RC's you'll be able to lease out) posts do seem evergreen in that sense, unless of course you're selling everything.
On top of that who's to say front-ends like peakd won't at some point introduce adrevenue sharing with the authors. You're right, though, that authors should attempt to SEO their posts better, it doesn't require a lot of extra effort and even though there's no evergreen right now, it'll easily could be added in other ways in the future. Not like rewarding an author for old posts is that difficult to do, not like you need to vote up the same post, if they're active you can cast them a vote on a new post or a comment (linear curve coming up making that easier) and of course there's also feeless tipping.
So what I'm trying to say is that evergreen active post rewards is kind of overrated. :)
