This morning I couldn't suppress a grin when I stumbled upon a website called Woolygans:

Woolygans is a new type of social network dedicated to all aspects of street culture and extreme sports: street art and photo, underground music, fest videos, crew blogs, cultural events and much more!

It looks like they're modern daytime hippies as they have published their manifesto on the site :

The bottom line is that as the world around us is becoming smaller at an unthinkable speed, we are separating from each other even more quickly But we still believe.

This initiative looks like an interesting one. Social networking is not new - but social networking for a specific group is very new. Check them out.
