So, like, I am going to totally cop out and say that there are too many people, that I would like to meet, to name.
And then, like, I am going to list those that come to mind with the most haste:
Eric Noah - As the grand patriarch of our online community, and as a generally cool guy, is someone I would certainly like to meet. Not to mention he is also a teacher, like many in my Dad's family, so that is pretty neat.
PirateCat - When I think " storyhour " , PirateCat's is the first to come to mind. Also, his is one of the few games a suggestion of mine ever perhaps made a lasting impact on. With the dearth of updates, I'm also curious as to whether he has gotten any more mileage out of it since the defeat of the White Kingdom.
Sagiro - As far as I can tell, conspicuously missing from any other posts, up to this point! Author of the second storyhour that comes to my mind when I think on the subject. I envy everyone in his and PirateCat's powerhouse gaming group their two awesome DMs. That he is also a game designer and has voiced a few characters is cool as well.
Sepulchrave II - Because the level of detail and philosophy is his storyhour is simply amazing. Truly the standard for epic ROLE-playing.
jonrog1 - Not sure whatever happened to him, other than fame and... umm... infame...

He also had a cool storyhour, probably not surprising, given his profession.
HellHound & MikeBr99 - Because they grew up or are within spitting distance of where I live, and yet despite having come here for many years, have never met them.
