I am shocked and saddened by the news. Aaron and I met at a conference around 10 years ago and quickly became friends. Although we lived in different countries, we made an effort to meet when we happened to be in the same city and kept in touch on Facebook. He was a dear friend, funny, generous and kind. I'm happy to have had a chance to know him and so sad he's gone. My thoughts are with you, his family, at this difficult time. Know that he will be sorely missed by all who knew him. Go in peace, Aaron. Much love.
