Oh, and also - this morning FB suggested I may know the Lyft driver from last night. I wasn't even the one who ordered the Lyft, I just rode in it. I don't have the FB app installed on my phone. WTF?
For that, I was under the assumption that the 'People you may know' on facebook was also who had been looking at you on Facebook, so the driver might have been looking you up.
How would he look me up? He didn't know my name. Can lyft drivers see the full name of the people who they pick up, or just the first name? If they can see the full name, then MAYBE he looked up my friend, then looked at his friends list and found me. I find that extremely unlikely. I've also seen a lot of very, very strange "you may know" suggestions for people that I've only met in passing, and again without full names.
