I always had the feeling that 9 out of 10 startups in Berlin are founded by business students from private universities like WHU.
Is this a misperception or is the hacker-businesspeople-ratio really better elsewhere?
I can not answer your question, but I want to add that Berlin might be the city with the highest hackerspace density:

The whole Bay Area has.. not that many (well, they have one biohackerspace).
I'm not from berlin, but my perception is the same. There are a lot of smart hackers in germany in general, but many of those do software for fun or idealism.
Because there are not many VCs in germany, those VCs (i guess) don't trust tech people as much as business people. There are a lot of successful ecommerce companies in germany, a little number of tech based (wunderlist/soundcloud) and a lot of stupid social networking companies that make no money at all.
I could be totally wrong, but that's my perception.
This was strongly my impression as well. A bunch of business guys who have seen The Social Network a few too many times chasing the worst ideas imaginable.
