tenderlove is the best. Not only does he work on both Ruby and Ruby on Rails, he's also very active in the community (conferences, workshops, talks) and working hard on promoting a spirit of humility and respect (see the humorous Adequate HQ, the Friday Hug, the overwhelmingly positive and generous attitude he's always had towards anyone, famous or not, in the Ruby community). I have nothing but respect for that man and I'm glad he's working hard everyday on the language I so love.
Thank you Aaron.
