I was horrified and humbled to see that the people making this amazing stuff are making considerably less ($2k/month) than I do... or frankly, than most of us here on HN do. Their impact is so much bigger and I aspire so much to have as a deep understanding of the Javascript world as they do.
Maybe they'd do better operating out of of somewhere cheaper. Many older open source projects including those I contribute to aren't owned by a single company, aren't trying to build a business and still manage to be popular and useful.
