YC is great because you get environment and advise from people who were part of successful startups. Also their connection helps. After the rejection - it is better i do my work myself and then if needed - for connection and advise - I will apply again in YC for next round. You might be next BillGates or PaulGraham but at this time you are just like me and other developers who wants to be their own boss. So, as you don't have proven track record - I am not gonna move to SV just so that I can stay with other like minded. I am motivated enough to do same by staying at my place. I might be wrong but people should rethink about what they wanna achieve by moving...
