Just in my personal life tonight:
A friend contacted me via Facebook to see what I was doing.
We met up at a bar, and we then used Facebook on our phones to get in touch with several other of our friends, who then met us at the same bar.
We then posted a couple pictures on Instrgram and shared them on Facebook because it was another friend's birthday. I ended up having a lot of fun.
Without Facebook, I would have stayed home tonight. Maybe done some laundry.
