According to Gawker, someone recycled a Los Angeles Times story from May 2008, when the Supreme Court overturned an earlier ban on gay marriage, and packaged it as new news. Of course, Prop 8 was passed in reaction to the ruling reported on in the May 2008 story.
That fact didn't stop the misinformation flame from spreading. Gawker reports:
But Twitter doesn't sweat the details! Thousands of users "re-Tweeted" it or whatever, and before you know it, the Los Angeles Times' own fucking Twitter feed was sending the gay marriage news out to its 19,700-plus followers.The Times has since Tweeted that the earlier Tweet was not new news. FishbowlLA also issued a correction on its website.
