Fareed Zakaria's being accused of plagiarism and apologizing for it brings a related question to my mind.
There are lots of Big Names who appear on television, write books and columns, maintain Facebook pages and tweet every twenty minutes. How much of that do they themselves do?
I blog, tweet, maintain a few conversations on Facebook and via e-mail, and have several other things to keep me busy, some involving writing. I produce one or two blog posts on a good day and perhaps a dozen tweets, including retweets.
Are the Big Names producing all the material that has their Big Names on it? Could overworked interns be part of the plagiarism problem?
