If you're in Scotland, you already know it exists and would automatically be looking locally. I see the London meetup as "poaching" people to come to Scotland.

I'm moving to work in Scotland myself very soon. I've got a weird range of reactions from people here in the south of England; people are sort of suprised to learn that Scotland has electricity let alone a tech industry.

The most effective recruiting strategy would be to ask people what they're currently paying to live in London and how tiny a flat it is, then show them the corresponding 3 bedroom house / Georgian townhouse they could get for the same money.
