While i do support terracoin i think the issue of someone poining asics at the network and thrus forcing up the difficulty of a reletively new coin shows a major flaw in most alt-coin designs - using the same algorythm as bitcoin, imho any alt coin that wants to stand the test of time and actually be taken seriously is going to need a difference algo - take litecoin as the perfect example, different algo and it's followed the same mining evolution as bitcoin.
First CPU, now GPU - next someone will develope an FPGA and eventually it will probably go ASIC - this is how it should be. it shouldnt run the risk of being killed off in a matter of days because someone pointed a high end mining device at it.
The lesson i think that should be learned is that now ASIC's are out there, if you want a serious alt-coin then dont use the same algo as someone else.
