VB News posted interesting article. They analyzed data from StackOverflow where coders exchange Questions and Answers. Users of the platform vote up or down answers to questions this way ranking the coders who answer the questions and problems posted.
Their analyze shows that London has the highest number of top Stack Overflow members, with 394 that have a reputation over 5,000.
Another ranking based on the average country ranking of Stack Overflow users above the 5,000 threshold shows that Bulgaria has the highest average reputation among top users in the
world.
I have no idea how correct is this analyze, but I’m glad to see finally something IT related, where Bulgaria is #1 in the world 🙂
