It's a rotating roster of credit, proportionally allocated by donation amount, so it can be a weird little easter egg to see what sponcom decides you "sponsored" in a given month. Like, for example, this week, friend of the show @jacob apparently sponsored this helpful little improvement to internal maintenance documentation https://github.com/glyph/Pomodouroboros/pull/69/commits/03c0179753b9a58306152462fc8dcec5d9b70030 and also… for the best example of why this is not intended to be taken too seriously, whatever this mess is https://github.com/glyph/Pomodouroboros/pull/69/commits/7e7ab79f43773856de2f7078f7a7a375f02aaa6e
