I used to read his blog. Here's something I will always remember. When they sold Reddit to Conde Nast, back in 2007 or so, Aaron Swartz wrote something about it on his blog, saying how he felt about it and how he didn't have to worry about money anymore, etc. And then he decided to give away some money to startups in need. I replied to his blog post and he gave my old startup a $100 donation. It felt really generous. RIP Aaron.
