Ask HN: Where are all the London hackers working on startups?

At the London HN meetup last night I was amazed at how few people raised their hands when the group was asked "who is working on, or planning to work on a startup?".

Regardless of how one defines a startup/how the question was phrased/whether people just didn't bother to raise their hands, am I wrong to assume that a room of HN faithful should have more than ~5% of people trying to turn their software in to viable businesses?
