Even NXT is a great coin it will still fail just because of its extremely unfair distribution. The developer should blame himself to use this terrible distribution process. For pure POS coin, fair distribution plays a big part in these coins success.
why? distribution by a small group of miners right now more and more centalized in Iceland facilities and huge GPU / ASIC farms is unfair
Distribution by the cuckoo728 proof of work would be pretty fair, and low-power to boot.
That uses 7GB of memory (with no trade-off for time) which doesn't fit in any GPU card,
let alone ASIC. So anyone with a high-end desktop can mine this.
Or anyone willing to rent some cloudservers.
At the same time, botnets will not dare run anything using so much memory as it
will send computers into swap-hell, killing performance and alerting their owners.
It's also very power friendly since 95% of runtime is memory latency.
See

So we have winner for few month with distribution till it will be popular.
