In academia, that would still be self-plagiarism, so I personally wouldn't do that unless there is value added to it - maybe it is a different take on the same issue, some improvement to the initial idea presented, or something like that. Even then I wouldn't just put up the original post in quotes with an extra comment below. I would re-write and reformulate it.
And personally, I don't think considering something undervalued is a good argument for posting it again - it is a community decision, and how much you earn is what the community thinks you deserve to earn from it.
Oh, I agree with you on those points. I wouldn't repost the same thing either. I just meant I don't think there's anything legally that would stop him from publishing his own work again unless it is against Steemit ToS. If the user owns the rights then they are free to decide when/how to publish their IP.
But yeah, if you think the topic was undervalued or your article just didn't get the traction you thought, I would try to rewrite it from a different angle. Sometimes the internet is just odd though, things that you think are small go viral and things you think are going to be big never go anywhere. Such is life :).
Oh yeah. Life is unpredictable. Two days ago I was busy reading for my research, yesterday reading about bitcoins, today - I am a registered user on steemit. Gosh! =)
Indeed, only just discovered Steemit yesterday and after some googling figured that I would give it a shot and maybe get some beer money!
