securitas writes "The Washington Post has bought online magazine Slate from Microsoft for an undisclosed sum believed to be in the millions of dollars. The sale comes almost five months after Microsoft put Slate on the block (Slashdot) in late July. If you're looking for a perspective from someone other than Slate's editor Jacob Weisberg, Washington Post media reporter Howard Kurtz writes about the sale: 'According to ComScore Media Metrix, washingtonpost.com drew 4.5 million unique visitors last month, while Slate drew 4.8 million.' David Carr reports in the New York Times that Neilsen NetRatings recorded 6 million Slate visitors last month. Either way, Slate's audience is larger than the Post's online edition.
