Am I the only one who cringes when reading stories like this about the Valley? I do not want to be in a bubble. I do not want to take part in gossip or the popularity contest. I would much rather stay under the radar, out of the sights of competition, in an underserved market.
We do miss out a lot of startup action but there are still large startups in Europe, and I assume Singapore. I do think making connections via HN/Twitter etc can mitigate some of the issues caused by geography but not entirely.
Talking to people in your industry (especially if your speciality is quite niche) goes a fairly long way. Perhaps someone in your niche went to your alma mater, or lived in Singapore - that is something in common that can spark a conversation.
