Thanks for sharing your thoughts. I went ahead and implemented part of (2): letting the user who posts to rate. I'll work on ranking posts by this score.
Can I contact you by other means? Email or some instant messaging? I can sent you an invite to my little alpha.
People of course might abuse the rating, so the question is if one should normalize or at least fine-tune by having rating up and down in your own feed. And if you sort just by rating, without decay, a new user sees ooold posts at the top (because he has not dismissed any by going to the next page).
Won't it get annoying if new posts of lesser ranking keep showing up first?
And if you're up for it, let's chat a bit or skype.
Can I PM on foolow?
