If these relations between people and their information remain forever
and remain being updated, I bet we could make money selling
visualization tools. Take some psychedelic colors for the viz, get
some people hooked on the concept so that the Mana starts flowing, and
we have the perfect mixture between an LSD trip and Facebook.
Guaranteed gold. Wonderful use case for video glasses too.

In all seriousness, I wonder how feasible it is to keep updating
everything. It seems to me the computational complexity explodes with
the number of points and the number of participants. Doing on-access
evaluation of a reasource's "Mana score" may introduce high latency,
destroying part of the experience. Proactive updating has the risk of
triggering a system-wide update storm. A propagation cutoff (dropping
Mana updates once the delta gets small) seems in order to limit the
extent of updates but that introduces the risk of introducing
unfairness, when 10 updates of 0.1 get dropped but 1 update of 1.0
comes through fully.

Still, interesting concept.

Regards,

Jens
