What data have you needed as a developer lately?

Question

Database

Hey Habr!

Interested in this question, what data / databases have you been looking for lately?

For example, your application needed lists of countries, cities, or some addresses, maybe something else.
Maybe some site was parsed for this.

I'm interested in this for market research, to create new useful products.
