Well, one person not on the list who should be there is Modulous. He's got it all--insightful posts, often providing interesting factual information, seems good at understanding multiple perspectives, writes concisely, and gives off a calm feel.
Mod should be up there. My vote goes to Modulous.
I won't even attempt to comment on all the other great posters we have here, just to say... thanks all for helping further my own thinking! I'm looking forward to what lies ahead in 2006.
