I think you've made a strong
point, and then shown why that point doesn't work."There is one, and only one,
gTLD that I would agree benefits the Internet community at large..."
So, imagine
how many other people feel that way, except, it's not .xxx that they feel is "right".
Also, I don't think "everyone loses" because of confusion. There will be
more names, yes. But there will be more names anyway--weird domain conglomerations
within .com,.net,.org -- that's confusing! So, open up the TLDs: ccTLDs
& new gTLDs will expand the market and speculation will diminish.
