I've been sharing my decision to leave my current employ with co-workers and colleagues. Their kind words have been deeply touching, to the point that I risk an ego-out-of-bounds error. People couldn't have been nicer if they'd been asked to speak at a funeral.
That's the hardest part of leaving this job: all these wonderful people. I'm excited about what's coming next, but I will surely miss the company of this world class group of thinkers and doers and just downright nice people.
