For a coin to succeed long term it needs a community supporting it and developing for it. Coins that don't have this risk falling into the whole pump and dump scheme.
Yeah that's one reason why Feather will survive in the long run, the dev is accountable and he's active on the forums. Most of these other coins are released by first-time poster accounts. The guy who released CNC didn't even come back after the coin was released. It's hard to believe anyone interested in releasing their own coin didn't already have an account on here. I mean yeah, I get wanting to remain anonymous but that really does you no good with all the competition out there. Don't compare Satoshi and Bitcoin, quite different.
Look at other major alts like Litecoin and PPCoin, both released by devs that were active in the community and don't hide behind an alias dedicated to their coin.
