Continuum 2012 Attendance Chart

I think that this chart based on the current signed-up members of Continuum 2012 is very remarkable. Whilst we still have a good portion of the 'old guard' still attending the Continuum, we have over half that either have either attended twice, just once or are first timers.
It will be curious to see how this changes as the convention fills up closer to the time as we only have about half our attendance signed-up currently.
