Another quick link roundup

I like being busy, but it does take time away from lower-priority pursuits like blogging. If I had more time, I'd pontificate on the following:

• Paul Krugman wonders why Paul Ryan is taken seriously, as do I;
• Chris Mooney and Kevin Drum wonder what about the Republican brain makes them so opposed to facts;
• The Atlantic Cities has a fun gallery of world subway platforms; and
• The Times examines the ridiculousness of taking laptops out at airport checkpoints.

For now, though, it's back to the mines.
