I suggest we also consider the ideas for extending the basic idea (in
ways that don't require fancy new systems). My folks would like to
figure out how to create a Spot-us that builds (and depends upon) non-
geographical communities.
Also, there are variations on the theme that might be easy to do. For
example, here's a similar idea, but designed as a contest. In Spot-us,
such a "contest" might be a request for pitches on a theme, in a
topic, in a timeframe, in a place. (see
http://www.nameyourdreamassignment.com/the-contest/)
Again, the wiki should have space to develop these ideas.
