Because they now have money to do cool stuff?

perhaps they like their work

shill. or fan, prolly. i don't use the more current word fanboy. ugh.

(when older words are good enough, why invent a new word. but I see that as a trend. each new generation wants to distinguish themselves from the past one. So they invent new words as one way of doing that. and some of them get adopted into general circulation or use.)

Unless the two words, fan and fanboy, mean the different things, which i'm not interested in checking out anyway.
