Unfortunately, Kevin Drum's prediction is probably dead on
a fellow with the Twitter handle @FootyTube_ quickly changed his handle last night to @Dzhokhar_ and swapped out his avatar for a thumbnail of the suspect in the Boston bombings. That's hilarious!
Or not. But I predict a growth industry in this kind of thing. FootyTube's idiocy was easy enough to see through, but someone out there now has the bright idea of creating a Twitter/Facebook/Tumblr/etc. account and populating it over time with grievances of some kind. Islamic, gun nut, anti-tax, libertarian, PETA, whatever. Just create a nice long chain of posts and then wait for the next terrorist attack. As soon as pics and names are available, switch the account name, make it public, and wait to be discovered.
