Blockchain.info themselves didn't get anything from you - but for some reason their wallet decided to pay around 10 times the usual fee of 0.0001 BTC.
I don't use their wallet myself, but seem to remember they have a setting for how much fee to include. Did you perhaps select the "generous" setting? I can't think why else they would include so big of a fee.
YES! dooglus you are a genius detective. I am logged off BlockChain.info now, and will check my settings later, but as I recall when I set up the account I checked the "generous" checkbox thinking it would speed up transactions (since I had read that some
BTC transactions take 1 hour to confirm.
So you solved it, I'm 99% sure that is what happened.
