I've had an inkling at various times to make a widget or app or something for players of Diplomacy [0] that uses this visualization to make it easier to see activity in all of your conversations at a glance / select who to talk to. It always ends up being more of a 'fun' idea than something that would actually be useful, though, because the 6-set Venn diagram is so much more difficult to visually parse than just a list of countries in a "To" line. [0] when played with "white press", which is where players can send messages to another player / to multiple other players, and the source of the message is authenticated. This is in contrast to "gray press" where the source is / can be anonymous instead of authenticated and "black press" where the source can be spoofed.
