This is actually an alt. coin with huge potential. The network seems quite stable at the moment, with a reasonable difficulty structure and GLDcoin seems to be building up a dedicated following. Despite the pre-mine the total number of coins and the reward structure should provide some longevity. Congrats to GLDcoin - this one really is a gold rush!
I hope that development continues, its clearly partly built from feathercoin, as you can see when you encrypt the wallet in the current (1st) windows version compile.
Anyway I'm mining some GLDcoin with my 100+ kh/s scrypt box over at gld.vircurpool.com
I think that Goldcoin could be popular with the masses, over some of the other alt. crypto-currencies, purely due to its name.
Doing quite well on the coinchoose.com leader board as well presently.
