People generally wear rings to indicate that: a) they're married b) they're about to be married [1]
Both of these rings traditionally use the same finger. There's a lot more information potential in the information broadcasting apparatus.
I propose that a new cultural system be established to make use of the remaining bandwidth. In general to be a useful indicator, this should be information about the wearer which:
a) doesn't change very often b) applies in some form to a significant proportion of people at some stage c) Is either boolean or a small positive integer, d) is useful or interesting in conversation, e) is not generally held private, and f) where presence or absence of ring(s) is not an issue for non-players.
Without making this a request for a list, I can say that I can't actually think of 9 such items. However, here are some:
a) Child finger. One ring per child. b) Hobby finger. Any personal interest may be indicated with a stylised ring on this specific finger.[2] c) this idea would be more convincing if there actually was a 'c'.
Um, okay, that's it.

[2] This is not intended to preclude the whimsical wearing of rings by non-players, but rather to ensure space for such use within this system.-- Loris, Feb 01 2010 [zen] You could even have one finger reserved for coloured rings showing your resistivity.
