I believe just about everyone has something to offer. Whether it is his or her idea, life lesson, advice, creativity, etc., there have not been too many who I was unable to learn SOMETHING from.However - I must admit I enjoy meeting "mad geniuses." And nonconformists. And free-thinkers.EDIT: Who I'd REALLY like to meet? God. I'd be scared to death, but I sure would love to have a conversation or ten with Him.UPDATE 9/17: I'd love to meet & pick the brains of plenty of musicians, authors, actors, actresses, political figures, and other types of world-shakers - wouldn't we all? Of course, some reasons are more savory than others - for instance, Cate Blanchett. I'd grovel at her feet in awe. I'd also love to see Gerard Butler nude in person as he looked in 300. Or shoot the shit w/ Oprah and tell her how she should run for president. =D No, I couldn't meet our current president. It would be too incredibly hard to fake a show of respect.
