well, I put some research into it before I invested in those first half a dozen 5830's

already knew what difficulty was and that it was ramping up quickly (but that was also when price went from like $3 to $35)

and also knew  to switch to namecoins when they first started too!

plus, it's $1000 or so vs $6000? 

a poor sap like myself that considers $6,000 a good chunk of money would make sure to research such things first
