Here's a quick list of common HN comments about Facebook announcements so that we can get them out of the way and actually discuss this product announcement:

1. I don't use Facebook.

2. It's been X years since I deleted my Facebook account.

3. Facebook is a threat to democracy/society/open web/news

4. Something something stealing/selling/sharing data.

5. Something something tracking users.

Reminds me of reading the comments on any article about Microsoft on Slashdot 20 years ago.
