I'm interested in any evidence (even anecdotal) that general Internet usage (and more importantly, link utilization)

Growth unsurprisingly also varies by region:

It has seen plenty of growth recently.

If any MSK-IX staff reads this, a 3-, 5- or all-year graph would be an
interesting add!

I don't know if that proves your theory.  And one could argue public IX stats are actually not representative of 
growth, since many networks move peers to private connections as they grow.  But it is data, and it is available.

Aggregate IX statistics also fail to identify what part of the growth
is due to people moving traffic onto IX:es, from private connections
(transits).  It is certainly data, aggregate data. I wouldn't hang my
heart-lung machine off of it's accuracy in predicting individual
networks short-term traffic developments though, so to speak. :)
