Here's an interesting article from the Communications of the ACM, May 2003 (v46i5: 71-75): "Of Course it's True; I Saw it on the Internet!" I find it particularly interesting because it's sort of an acknowledgement that even CS students need to develope information literacy and critical thinking skills when it comes to finding stuff on the net. And it even comes from CS scholars! There's what seems to be a slightly different version here.
