Wow, that is a very cool tool. I actually rank pretty high myself on that list - JUST shy of top 20 - and I also have no interest in selling at this point. I'm a noob, so I haven't developed any deep loyalty yet, but there is definitely lots to like and I lack the nerves to be a day trader anyway. I'd say I have a serious crush but am not sure Im ready to settle down and be exclusive with FLT at this point.
just wanted to mention the top address in that link that currently has 33 million coins is the bter exchange cold storage. when people first see that link they sometimes think it's someone with a huge chunk of coins but it's definitely bter exchange. second is mintpal. the other big one that came up the last day or two might be cryptsy.
