The enthusiasm described by the author feels familiar! Every once in a while I send emails to 'random' people without expecting too much. During covid I emailed a C64 developer why a certain enemy type from one of his games in 1986 had a certain name. He responded a few days later with a lengthy and in-depth explanation.

Last week I saw and photographed a sticker with street art near my office. I tried tracking down the artist (he was from a neighboring country), found him and tried to find some contact info. I emailed him if he knew how his art reached my city. He answered that the art piece on the sticker was something he created 30 years ago for a festival and that - apparently - an unknown person made stickers using his art.

Sending a short email does not take a lot of time, but it's very rewarding when the other party answers.
