it started at around block 600 for public miners
dont know what was with earlier blocks (premine for IPO maybe?)

and it looks like the adaption of block difficulty was to slow for the big starting hashing power
so networked solved the low difficulty blocks faster than expected

now with higher difficulty block time seems to be at least close  to 2 min with 1min31sec

if on average block solving time will stay faster than 2 min i still see no big problem just adapt coin describtion
at the moment it look like 90 sec block time
