Seconded. Moving here will help you find a cofounder, meet lots of other entrepreneurs who can help you, and build relationships with investors. The economic benefits of being involved in the startup scene may outweigh the high cost of living.
Which is why I advocate splitting the difference, and moving there once you can already survive. Ramen profitability is a great boon to negotiations, remember.
"Moving here will help you find a cofounder, meet lots of other entrepreneurs who can help you, and build relationships with investors." Can you share some specific experiences (how you met them, how they helped you, outcomes,etc)?
