I'm guessing because he wants to learn first-hand what you're talking about and you like to teach. You both want to teach what you know; maybe a better question is why "wouldn't" you want to get together and compare notes?
In the spirit of "togetherness" () I would love to see you two get together, if for no other reason than to show how two apparently different ends of the spectrum (per the written medium, at least) can find commonality in training. I'd like to know your take on his way of moving as well as his on yours.
To be clear, I'm not interested in right or wrong here. I'm of the school of thought that all opinions hold validity, so even if you two came away with different opinions on the nature of "aiki," it would be valuable to the many many comments you've both had on the various topics related to aiki.
You both strike me as magnanimous people. Put that to the task and let aikiweb reap the rewards. You can always still agree to disagree.
Sincerely,
Matt
