What we saw with FTTH deployments is that customers uploaded 
more videos and photos to Youtube, Facebook, MySpace, e.t.c. 
They didn't do this on ADSL as much (it's too frustrating).

When that caught on, customers started buying online backup 
services - synchronizing backups of their home or office 
computers to remote backup infrastructure. Again, they never 
did this with ADSL.

What we learned: don't take it for granted that you will 
always know what your customers (or the content providers 
who serve them) will do with the bandwidth. If they have it, 
expect the worst, and plan for it as best you can.
