This is not say he was not a thinker as well. It took a while for me to get his humor, the depth of his nuanced sense of irony -- should I say sarcasm? He gave me some grief a couple times, and I was not sure how to take it. So I asked, and he told me. There may have been a time or two when I am rubbed him the wrong way, or he wondered what I meant by something. He would ask me about it, and accept my answer. He was not one of those who would try to tell me what I was really thinking. He might have disagreed with me, and e-said so, but did not try to put words in my mouth. He also seemed to accept disagreement without being excessively disagreeable.
One thing I began to notice about Greg was that it was not all about him. He was apparently genuinely interested in others, what they thought; what pushed their buttons; what made them tick. With some of the personalities one encounters on line, or in real time, they seem to feign interest in others; when it is really about them. Greg was definitely not like that. There was a time, in a study groups, when someone took something I wrote the wrong way, and a tiff started. So, in jumps Greg, explaining exactly what I had intended. Then the person who had given me as hard time slithered away and hid under a lotus pad. Meanwhile, I was not even aware Reverend Greg had been following the discussion. I thought that was impressive. He seemed to keep track of a lot of things going on in the cyber groups, he had the pulse. I suspect he had a very busy, rather adventurous 'real' life as well. The ability to keep track of so many things, that well; that accurately, can only come from genuinely caring.
I guess that; a combination of caring, boldness, and a do it now enthusiasm, is what enabled Greg to bring all of us, those who blog here, together, under one accurately named heading. It was truly a feat that was fraught with peril. He seemed to live Daisaku Ikeda's advice to be bold and courageous; even if doing so was not always welcome within SGI. If Greg had any agenda, other than getting people, those with diverse views, talking with one another, I never had a clue what it was. I do not even know his political views were, what kind of music he listened to, his favorite movies, and so on. I knew he liked martial arts -- duh!?! I was not even aware he was a scuba diver. I now know, from an obituary:
Greg was the vice president of Andrews 
Blueprint. He was head instructor of
Bujinkan Wako Dojo, an EMT, former
member of the Santa Clara Vanguard
Drum and Bugle Corp, member of the
Buddhist organization Soka Gakkai
International (SGI-USA) and for 22 years,
ordained minister in the Universal Life Church.
