Most of the things I think are cool fall well outside of the mainstream. Freethinkers are cool to me, not trend starters.
I remember when revenge of the needs came out. It made nerds 'cool'. What it really did was make being smart and different acceptable. There was the smart guys and the gay guy and the dirty pre hipster guy (booger). Different became mainstream. It created the awareness of niche groups in society. Nerds became aware the they were not alone.
Now there are sub groups of groups. Subnerds. Subgeeks.
Normal has been worn out. Everyone is willing to admit their geek side. Comic collector, MST3K fan, Trekkie, audiophile, maker, whatever it is. Is it good?
It's fucking great.
