Just having a Hacker News meetup has helped London a lot i'd say, it's helped me find like minded people as I found there were a lot of 'old business' and finance folks going to the events that weren't designed for what they wanted to do in business.
London Hacker News is now the biggest (or top few) monthly startup meetup here.
