How many photo-related startups has Facebook acquired now? And what do they gain from Instagram? A user base? Most of them are probably already on Facebook? Technology for handling photos? Doesn't Facebook already do this as well as anyone else? Design and UI talent for mobile apps? Don't they already have Mike Matas?
Most of Instagram's "technology for handing photos" uses S3, as described in previous Instagram tech blog posts. Instagram however has a massive big data structure which would lead to any big company getting high value out of them. Why use the tools they open sourced last week to improve your reliability if you can just acquire the entire team?
