In a sense, the blog is the antithesis of my academic training. Universities are about restricted knowledge. We study our own things, keep our research to ourselves so no one will steal our work, and we publish results in journals in a language no one understands. The idea of blogs is all about shared knowledge. I love sharing and getting feedback on my findings, and this blog has introduced me to so many fascinating people from all over the world — students, scholars, urban farmers — and it is really interesting to hear their takes.
