Jason is a great martial artist. He actually puts his body on the line to test techniques and fighting methods. I respect the fact that he's trying to breath new life into aikido with his hard earned fighting perspectives and personal interpretation of the art.
The man has skills, and attributes, and the fact that he teaches groundwork as a complement to traditional Aikido tells me that he's both open minded and progressive.
He's had some impressive wins, and some losses, and some injuries. He's been around the block and I think the Aikido community should be very happy that a seasoned fighter would be willing to invest himself in this beautiful art.
Just my 2 cents.
