Me!
But as far as players I admire, I would have to say I like Doyle Brunson before he got all preachy. Super System is a staple in any poker players library.
I also like Negreanu, I've read his books and don't totally agree with all the details of his play style, but it clearly gets results. He was also in that one poker movie, I had a laugh when a newb berated him in that one. Other than that, he seems like a nice guy.
Pure joy to watch though? The poker brat. It's like a train wreck, you just can't look away when he starts on a rant.
Thinking about the poker boom of the mid naughties, I think it was really fueled more by the personalities that were popular at the time more than Moneymaker cashing. Sure, moneymaker sparked the interest, but it's those personalities that kept the hype rolling.
