Did you read about that guy recently who sent 800 BTC to an MT Gox address? Crazy stuff. You'd think someone would take a little bit more care when sending that amount of money.... 
Really? I didn't know that...
EDIT: I found the story with google.

Yeah, that's why I tell newbies that time better spent would be familiarizing themselves with blockchain and wallet uses rather than chasing 10k satoshi at a faucet.
What the hell...He sent 800 btc (about $380,000) to an address that he didn't even know what it was...
You would be surprised how many times people have sent coins to the wrong place because they only look at the 1st 2 or 3 digits, or only the last 2 or 3.
Addresses are to be copy-paste, NOT typed in. Hand typing is always error prone.
Copy/Paste doesn't fix the issue if you select the wrong thing to copy, or if you think you hit Ctrl-C and you end up hitting CTRL-X or something. This was the discussion of the forums back in 2011 when the coins went from $1 to $30, people were killing themselves (figuratively) for losing thousands of BTC then!
That's true. But, I would expect them to double and triple check the address before pushing the "send" button, especially when they are making such a huge tx.
