Nice to see Lisbon on the list.
I see the positive side of keeping people there instead of having to try their luck abroad.
Actually I would like to see all district capitals enjoy startup fever, specially the inner country ones.
If it's a small, European centric scene, by Europeans and for Europeans which grows organically outward then it stands a chance to enrich the city.
Personally I'm not much of an advocate for Europe welcoming SV folks and their VC masters in.
