I upvote danluu.com because I consistently like the posts; at some point, the domain name becomes a marker of quality.
Dan Luu has an about page and a LinkedIn page, but he's not a mega-celebrity or Chief Architect of Google or some such - he's mostly a guy with an uncommon-but-useful mix of backgrounds who writes well.
Who is he? And why does all of his posts get massively up-voted?
Thanks in advance, from an ignorant chimp. :)
