Why I Deleted Facebook

• Because it's too easy to find yourself looking at random wedding photos of people you don't know.
• A few minutes wasted here and there add up a lot over time.  I can do much better things with that time.
• One of my Facebook friends was a fellow intern from NVIDIA.  We weren't super close, but I was surprised to find out that he killed himself two years ago, and Facebook never made that obvious to me.
• Facebook uses algorithms to attempt to determine what you are most interested in so that they can show you only that.  This means that Facebook's feed algorithms inadvertently have a huge influence over who you think about and who you interact with most.  Many of you will call this a feature, however, I have decided to control who I think about for myself, instead of outsourcing it to an algorithm.
• I already have my own web sites and servers, why don't I just host the content myself so I can control it?
• I trust that Facebook will never do anything bad with my data, it's the rest of the world I'm worried about.  In a world of move fast and break things, I expect that Facebook's security team is going to echo the root database password onto the homepage one of these days.
• Asymmetric social interactions.  It's easy to think you're close with someone because you see their face in your feed every day.  In reality, they might be seeing a completely different group of people in their feed.  Conversely, you probably have a few frequent admirers that you barely ever think about.
