newbies are not asked to put any money in, they instead might get paid. It is a backwards ponzi
whitepaper
https://steem.io/SteemWhitePaper.pdf has some very interesting concepts and my feeling is that it is all dependent on userbase growth
clearly the $1000 payouts for posts cannot be sustained, but at scale $10 per post likely can be. So the question is how will reddit/facebook fare against a competitor without advertising that is paying for posts?
there is a non-zero chance of steemit success. What exactly this chance of success is, nobody knows.
As to the initial adopters having disproprotionate share, well what crypto can say otherwise? Over time the majority account is slated to be given away as signup bonuses and at that point the richlist will still be concentrated, but not more than bitcoin
ignore steemit at the risk of missing out on the first mass market crypto. It isnt perfect, but it does seem to be better than the competition and leads its category for now.

P.S. I might be biased toward steemit as my intro post received $15,000 in upvotes, but I view that as a consulting fee and it was enough for me to investigate further to identify its weak spots. My typical post now averages close to $7.77
