That picture with Facebook photos in comparison to the other major sites is impressive, I didn't realize they had that much dominace. In other news, please, we haven't (IMO) solved the photo sharing/storing software problem. Snapjoy is close, but until I can have public photos, face (people) based grouping, and tags/event organization, it's not there yet.

That image is wrong and misleading. Facebook: 140000000000 photos Flicker: 6000000000 photos Instagram: 150000000 photos LoC: Wikipedia says 12000000 which is around the "Facebook has 10000 times more" so let's use that. ----- Let LoC be a square of 1 pixel side lengths. Instagram is 12.5 times as much. So the area would be ~13 square pixels, that leads to side lengths of 3.5 pixels. Flickr is 500 times the LoC -> 50…

Image is definitely wrong based on your numbers but I'm not sure it's "misleading". Your picture also shows a complete dominance by facebook. The difference is big, but not important for the purposes of the article. Especially when you consider how poor humans are at determining amounts of things based on area (see the recent discussions on pie charts).

Interesting. Incidentally, this would make a great Fermi type interview question, to replace how many gas stations or piano tuners are there in the US.

I still don't understand how a Fermi question makes for a good interview question. How can you make reasonable estimates about something you know nothing about?

I don't like those type of questions either, I said it would make a good Fermi question, not a good interview question :-) For some reason, some people love to ask such questions. I'd rather ask how to perform face detection on 1 trillion images.
