So what if suddenly tons of ppl donate money and we go way past the 2.1M goal (it can happen!!)? Wil there be a extra stretchgoal?
i dont think it will be reached and if, they just can take the money to make sure, that everything will be as awesome as they promise
while I seriously doubt that it would be needed, I'm sure they find something to put on the table: - early retirement - world peace - skynet ( http://what-if.xkcd.com/5/ ) ...
If they get passed $2.1m I hope they spend the money on beer or something. They are pushing the margins tight as I understand it. If they get a little extra then they should count that as opportunity to relax slightly rather than us demanding new squeeze goals. I think their current suggested vision is pretty much complete in scope (if not in detail). Any extra and you risk getting to the stage where deadlines slip or concepts clash.
