After reading the entire article, the guy only seemed interested in condemning NXT, as he has done many other altcoins, as he focuses on 3 things:
1) short account # invites passphrase collisions -- this can be mitigated by injecting alphabets or simply scale it up to 30+ numeric digits
2) initial distribution -- need we say more?!
3) lack of exchanges -- we are going on 2 and soon the major names

I suppose any coin that the author DOESN'T have a stake in, he feels the need to rub it in.  

Btw, he charges a freaking 1BTC for his so called premium content account.  1 freaking BTC!  

Obvious scam.
