I feel that GNU Terry Pratchett is a cute little harmless easter egg that can be easily implemented: https://gnuterrypratchett.com/

https://www.theregister.com/ have it for instance.

I also like the extension of this to other figures important to a community. I founded a community called MiloHax that centers around modding and learning from the game made by Harmonix Music Systems, and we serve X-Clacks-Overhead with Sir Terry's name as well as some other influential people, both inside and outside of the community.
