Every week there's some post like this, or "why I switched back and forth between Vim and Textmate 17 times", and, frankly, I just don't see the merit in it. Are you trying to get other people to use the editor you like?

As smart as the Hacker News set may be, most people are not experts in the field and could do with a little context.
Also, Aaronson's a well-known computer scientist, so this helps establish that the result's both credible and important in the eyes of people who may not (forgive me) all be qualified to judge the paper on its merits.
edit: Okay, rereading this article I recovered an insight that leads to a truer reason Aaronson's worth linking to. It is not that he's a famous professor (he is) so much that he is, in general, a great expositor. Read that big-number article and tell me he's not.

Anyone who knows who sjl is could have easily found his vimrc through his website. According to the bitbucket history, the file has been hosted there since at least 2009.
Did I say it wasn't useful? Maybe you missed my point.
I could post a link to a perldoc page for some builtin function, and that would be useful, and it's probably been around for awhile, and probably nobody knows who wrote it. Would you defend that too?
