that map looks good for USA but certainly looks wrong and lopsided for some places in Europe. 100K in Romania? I don't think so. In Madrid the average is definitely not 61K, more like 32 or so. Looks like they really don't have enough data for many locations, and maybe they just once had a job posted for that amount.
Personally, I receive a Startup Digest newsletter tailored for Madrid and BCN, curated by Alex Barrera, who I think is famous in the startup scene, and Maria Encinar. They cover jobs, rounds, events and talks...the usual. That might be interesting for you.
