Who is using Postgres?

NOT that you/we should _ever_ make a decision based on someone `else` using something, but as _humans_ we _naturally_ give "credibility" to something based on "_social proof_".

Mostly people (CIOs/CTOs) don't want to feel like they're making the "_wrong_" decision...
So having a list of "_successful companies/organisations use XYZ Tech..._" is _useful_ in "_high level_" discussions...


## List

+ Instagram
+ Skype
+ Uber
+ Spotify
+ Netflix
