This is not the first time my Twitter account has been locked. Actually, last time, my account was suspended, not just locked:
Twitter Account Suspended, With No Explanation
I changed my password. My Twitter account seems to be unlocked now. Hopefully I'm not just tweeting to myself!
Since I do have a tendency to post things that piss some people off, I gotta wonder: is some Twitter twit reporting my Tweets?
