While there been deals I regretted (spending BTC on random crap before it rose in value), in my case it's.. never!
I did however withdraw everything I had from inputs.io just three weeks before it got "hacked" (I simple had a bad feeling about having a part of my BTC in a web wallet). So it's been close. Too close.
I don't think the poll is indicative of the bitcoin community as whole though.
