In which I learn how to use a "computer"

I just figured out (with technical help from Jo and, randomly enough, a comment thread to Dear Prudence) how to block the Facebook news feeds of the few acquaintances who've accounted for 99% of the information I've gotten from that site over the past however many years there's been such a thing as a Facebook news feed. Thanks to having done so, I can now find useful info, such as the fact that a college friend who's also dating a physicist (yes, there's a club) is getting to go to a taping of The Big Bang Theory and going to meet Sheldon. See, this is valuable information.
