The "zones" are way too big.

For example working in west Germany is quite different to working in east Germany. The same goes for north and south Spain, north and south Italy, and so on.

We plan to work on city / region granularity and additional zoom levels. We just released this to gauge interest before going further.

It's not just by region, but at the city level too. There are often significant differences between salaries in capital cities vs others, as one would expect.

The cost of living is different, larger companies in major population centers have more capital, etc.
