This post triggered a wave of bittersweet remembrance: when Watsi was announced I signed up and was genuinely excited for what I thought a well-positioned incubator like YC could accomplish in general redistribution. I was very wrong! But to see this not being a shutdown or acquisition announcement is heartwarming. Keep linearly existing!
This post finally got me to dig back up the ultimate word trivia website, valiantly hosted on Tripod and still maintained: https://jeff560.tripod.com/words1.html
I remember doing this as a CSS copy-protection joke back in 2013. [1] Seems like a similarly petty thing for a company like FB to try and like many have said an extremely low-level arms race.
Reading your parent comment and the replies has me kind of dumbfounded at the wasted potential. Did they ever address these ideas directly? Would opening up the format in even the most limited ways (like focus) have exposed the IP?
Anyone remotely interested in this idea should check out Stanislaw Lem's His Master's Voice [1], which is an entire (short) novel about how and why an extraterrestrial message would be encrypted. It's worth mentioning how why turns out to be the most compelling question.
