I also think that the creation of more & more ICO's and coins is not needed. Around here, the whales already pass out "whaleshares" in the form of BitShares, which was, sort-of, the precursor to SteemIt. So, there's BitShares, Steem, SBD's, etc. already floating around here. I mean, if you REALLY want to reward somebody on SteemIt, you can already simply transfer them a Steem token or some SBD's, or give them an upvote, or a resteem, or a comment - or any combination thereof. There's already a TON of ways to reward people around here.
IMHO, people who are offering new ICO's on the SteemIt blockchain are simply trying to generate hype for their own project, which they would be at the center of, which could be very profitable for... them. So, all of this talk about "new ways to reward good content creators" seems to be a big smokescreen for a very simple character defect: GREED. I have to call it how I see it. SteemIt already works great with the transfer of tokens and SBDs - we don't need a $#!t-TON of new coins. What we really need is additional functionality built into the blockchain - things like a place to straight-up buy Steem and SBD with a credit-card, using U.S. Dollars, and not having to go through intermediate exchanges, first. Now, THAT would be a useful tool. Keep your new tokens - give me more functionality with what we've already got here.
I don't know that it is possible to build a Steem:USD feature into the blockchain.....I don't think it works like that. But building it into the frontend(storefront) of steemit, if possible, would be nice!!
Most of the rest of what u said....I agree! G R E E dddddaa D!
