Reminds me of the time the NYTimes swiped a collage illustration I made on my blog and ran it without attribution:

It took two emails of gradually-increasing emotional load -- I added the 'plagiarism' label to the second -- to get them to run a correction.

It wasn't a giant deal -- a recreation of another blogger's (Niall Kennedy's) concept -- but to see that just like any blogger, the NYTimes may just carelessly clip things from the web was eye-opening.
