Today start Campus Party!
 

Today starts in Valencia (Spain) the biggest concentration of internauts of the world, more than 5.500 persons with a 1'8 gbps connection (15% of all Spain connection).

It has a lot of shows, conferences (for example Neil Amstrong), etc

that sounds like the geek convention to me, but interesting.

I never go to this events, I only go to visit (I can't stay one week playing and sleeping in campings..).
