Like others have said,it is a good thing getting new and young fans.
There's no way of telling how long someones interest remains,
new or old to the act.
Those that remain active fans through thick and thin are very thin on the ground.
Getting new fans is essential since everybody's interest comes and goes.
The behavior of the fans is hardly the question of age.
There are million different ways of being a fan.
Being insanely protective towards your idol isn't a matter of age.
Look at Ledge,we all claim to be fans of Fleetwood mac,
yet there are clear divisions between fans of certain members of the group.
"I love FM's music,but i hate that member."
There's also the question of how do you define a fan?
I always remember from school a guy from my younger brothers class said he was a fan of a certain band.
He had only heard two songs by them.
I felt insulted at such suggestion,but many many years later
i've come to think,
we all have to start somewhere and there's no way of telling if that interest grows or fades.
Quite a rambling post,but there's a point,sort of...
