I've been crossposting a bunch since k00b rolled it out and I appreciate everyone who's dropped some crossposts in my various territories. The real potential of crossposting has yet to be tapped though. We're going to need two innovations to get it totally unlocked.
1) Crossposting existing posts
There's a trove of great posts on Stacker News that could have fit in several territories at the time they were posted, or would fit great in new territories that didn't exist then. We need to be able to unearth those gems by crossposting them into the other territories where they fit.
This will require allowing stackers other than the original creator to crosspost, which will require working out the right revenue splits.
Also, should great crossposting factor into rewards? Probably, but it's not obvious how exactly.
2) Allow old posts to become top posts (again)
Finding and paying to share old great posts will happen more often if there's an expectation that those posts will be zapped. Currently, people are reluctant to zap old posts because there's no reward incentive for doing so.
@SimpleStacker proposed a simple formula that would base top posts on which posts were zapped during the day, rather than which were both posted and zapped within the day. I'm not entirely sure how to handle the early zapping part with that, although for crossposts it could be the first zap after crossposting.
Is there anything else we can do to make crossposting better?
