I mean, I’m a pretty ADHD guy, very in the moment, and although I sporadically invite friends or old colleagues to catch up for lunch, I mean to do it regularly, but I might forget to invite them for years at a time, so this might be good for me. I could really used an “Anki for lunch”, spaced repetition reminders for people in my Rolodex, as it were.

You just need a tickler file.
