I think the reason it was doomed to fail is because it doesn't offer much over bitcoin.
it offers a few very crucial points over bitcoin for going mainstream, eg known creator (anon dev may be cool around here but not in the real world being real money, especially when said creator has a billion dollar + stash).
thing it offers over all other alts and the reason it stays a solid 2nd, no matter what FUD is spread here....TRUST.
