That change was actually made by the editor at Facebook, who did an excellent job of helping condense my original post and adapting it for a wider audience. I also added in the bit about "what are hackers and hackathons?":

If the words “hacker” and “hackathon” evoke mental images of scary-looking criminals breaking into computers, I can assure you we're nothing like that. Hackers, in the original spirit of the term, are programmers and designers who use technology to build things — not destroy things. Hackathons are events where hackers of all kinds come together to collaborate on new projects and compete for prizes, often on college campuses.
