I've noticed something interesting that puzzles me to no end...

How come, when I go to websites that showcase fonts for sale or free, and they display the fonts as a demonstration of how they look....yet... when I try to use that very same font, I get lack luster results. I tighten up the tracking on each individual letter (or loosen it if needs be) but when I use the same fonts I don't get the results they demo.
My text doesn't look as awesome as theirs. Why?
I'm still trying to figure this one out.....what am I missing that they know and I don't? It's still the exact same font! I can't be crazy. I know they are doing something....but what???

*Frustrated*
