Our round (Round 2) and @jot's (Round 1) each had 100+ companies, I believe another 100 arrive this/next week with Round 3 and we'll expect a similar nbr for Round 4. In Round 2 & 3 there were 600 applicants with properly-completed forms, if you're interested in the odds :-)

Personally I'll say that being here is very nice, it is great to avoid having to take on client consulting work to pay the mortgage. Things could be better (reimbursements, mentoring, access to more money) but things are a lot better for me than if I'd stayed back in the UK. I'm going to meet 1,000 pro-active folk out here in the following 5 months, I'd not find that many in the UK via my old networks.
