Busy day links

I had a lot going on at work today, so all I have left is a lame-ass "read these later" post:

• Cranky Flier wonders why Delta is Tweeting to individual passengers.
• James Fallows looks at Bob Garfield's latest book.
• Bruce Schneier says China isn't the problem in crappy 5G security.
• And John Scalzi has a new book coming out, which he'll sign if you pre-order.

I'd say "back to the mines," but I believe I have a date with Kristen Bell presently.
