Which cities (in your country) are tech hubs and offer many job or business opportunities?

I remember reading an essay by @rrhoover about how he moved from his native Oregon to San Francisco after university studies, where doors full of networking opportunities opened up for him.

I saw the same thing in my country after graduation. About 80% of my classmates went to the capital, where there are the most opportunities in marketing and tech. (Or they went abroad.)

The differences in places and their opportunities are vast and it depends on where you move (as my friend would say: "It's better to do business in SF than in Ghana.").

Which places do you consider to be the "Mecca" of business opportunities in your country?

I am in a very small country so I can list only 2 for Slovakia:

• Bratislava and Košice

[Idea: In the future, we could create something like a map of these places. 😄]
