The density/city comparison thing is really hard to measure, but I'd argue it doesn't make a whole lot of sense:<p>Since people are showing off re SV, I'll do the same for Chicago- where I've in the past couple of weeks met: CTO for Barack Obama (ran into at falafel place), Founder of Groupon (stood next to at Weezer concert sponsored by NEA, talked to him for a bit), Dave McClure (He's an investor in us, we had dinner. He comes to Chicago often and spends a lot of time with us because we were his only investment here until last month), VP from Motorola Mobility (architecture tour), State Senator from Ohio (bar), A Macarthur Fellow Architect (female, met at bar), Vice Chairman for Goldman Sachs Investment Banking (happy hour), etc etc etc.<p>Furthermore, just by chance (ie we didn't know this going in and it is NOT the startup hub area within Chicago), within 3 blocks of FeeFighters office are: 37signals, SproutSocial, Threadless, Crowdspring, and several other startups. I don't see how it helps us significantly to bump into them (though we have helped our neighbors when they've had merchant account issues). Many people think it is a wasteland anywhere not the valley but I have seen that not to be the case here, in New York, and even in Pittsburgh.<p>So what is the difference between here and there? The largest differentiator I've noticed between the valley and elsewhere is funding. We raised most of our money in Chicago from VC's we really like, but could have raised easier on the west coast. A lot of top VC's prefer to have you close and told us flat out they would fund us if we moved there. We had term sheets dependent on us being in Austin, SF, and LA. I don't think it has had an effect one way or another on our business thus far.<p>Startups need money, and often flock to where it is. Things are changing all over the place though (Rich people in Chicago all of a sudden want to fund startups, will be interesting to see if that continues post-Groupon IPO)
It also depends on your type of business. If you sell mainly to startups, you should probably be in the valley.<p>BTW in case you missed the discussion re: PG's original article, it is here: <a href="http://news.ycombinator.com/item?id=3077165" rel="nofollow">http://news.ycombinator.com/item?id=3077165</a>
