I did delete my Facebook account (this past week). I forgot to download all the data they had on me but I had a download from earlier in the year (maybe a few months ago) and that's sufficient enough for me since I made very few posts to Facebook this year.

In the lead up to deleting facebook, I deleted many "friends," removed all my likes, and deleted every single picture I could.

Unfortunately I can still be seen in pictures others have posted to Facebook.

I will admit that I still have Instagram installed on my phone. I could probably delete it and not miss anything but there are some interesting people I follow.
