Just read this blog post: http://www.immadsnewworld.com/2007/10/tips-for-founders-doing-their-first.html#links where visiting sillicon valley is being recommend for startuppers.
I have been wondering about that myself, but I wonder, how would it go down to go there? What if I went there for two weeks on vacation, would I be able to make any contacts, go to startup parties and so on? I am not usually the kind of person who makes a lot of friends easily and gets invited to strangers houses while traveling.
Of course, just to see some famous company buildings, hackers with their MacBooks at Starbucks etc. might be inspiring by itself. On the other hand I am worried about becoming depressed by endless roads and "Office Space" sterile IT buildings (you can see I have no idea what SV is like).
Any advice would be welcome!
So if you decide to come, definitely plan ahead.
