On Nova the other night, there was a segment about a man named Luis von Ahn. He originated the reCAPTCHA program, which--at least until I watched this segment--I thought was just a way of stopping spam by making sure I'm not a robot when I create an online account.
Little did I know that every time I have to verify my humanity on a site that uses reCAPTCHA, I am also helping to digitize old books and newspapers. Fascinating!
In unrelated news, what's going on with Blogger? I have had to manually publish this and yesterday's post (which was supposed to post on Tuesday) because they didn't publish at their scheduled time. Anybody else who uses Blogger experiencing this?
