Great article, Allen. I am a huge lover of traditional tabletop, and, like you, see a lot of value in using the 'net to further that tradition. Though Season 1 of GOLD [http://www.goldtheseries.com] pits tabletop against MMO, I don't think they are mutually exclusive -- a lot of MMO folks also play tabletop (Felicia Day of the Guild is a great example -- she plays a weekly D&D game). And whatever you think of 4e (and the opinions are widely varied), I can already see evidence at my local gaming shop that its simplicity, balance and updated tone are bringing in new, young tabletop role players (tho I haven't yet been converted ;-).
Tabletop has become the smaller cousin to MMO, even though TT came first, and inspired MMO. That's not gonna change. I just hope, through innovation and clever use of the 'net, TT will stick around, and in such a way that publishers large and small can continue to make a living producing great content. That's the thing we don't talk about as much, but it's a very real driver of the direction of the market: if small presses and innovators can make a living, TT RPGs will thrive. If you're constantly losing financially, eventually you will have to close your doors.
Obviously I'm hopeful that won't happen. And the $50 I spent on RPG stuff this weekend puts my money where my mouth is ;-)
