In case you read some weird tweets on my @rodrikdani account.... it seems to have been taken over or hacked (as of around 3:30 pm today). The password has been changed and I cannot access it.
UPDATE: I have regained ownership of my account. The attack seems to have been the work of a pro-Erdogan Turkish group ("Ayyildiz Tim") which has also hacked the twitter accounts of many others. The lesson: turn on two-factor authorization.
