I only respond to questions I like, so "good question" is always implied.

The sad story of why I am here: My friend Thomas died suddenly with a 30k+ reputation on StackOverflow. I was never able to find his username, but I was strangely proud of his achievement, because it really means he reached a lot of people. I never knew he was such an Overflower while he was alive. So I opened an account on Astronomy StackExchange and I'm trying to follow in Thomas' footsteps. If anyone from StackOverflow happens to know his username, I would be curious to know.
