Author here, sorry about the spikes where people do not actually live. A lot of users put only their country and not city, and I didn't want to throw that data away.
I probably should've checked the specificity of the location and only thrown out the data for large countries like Russia and China, or distributed it across all other data points in the country.
Thanks for the link, just watched it all the way through. I felt disturbed thousands of miles away - can't imagine what it's like to actually be there, so close to death and destruction every second of every day.
It's crazy that there are so many huge companies that I've never heard of. Instagram's acquisition was huge news at $1B, but I didn't hear a peep about Ariba at $4.3B or Genzyme at $20B.
It's easy to think that consumer oriented web startups are what's hot, but this data proves otherwise.
