The Washington Post has purchased Slate. I just got this press release:

WASHINGTON – The Washington Post Company (NYSE: WPO) announced today
that it has reached an agreement with Microsoft Corp. to acquire Slate
, the online magazine.
Donald E. Graham, chairman and chief executive officer of The Washington
Post Company, said: “Slate has been a pioneer in internet publishing,
and it is a fine magazine. Founder Michael Kinsley, editor Jacob
Weisberg, and Microsoft deserve great credit for creating Slate. We
couldn’t be more enthusiastic about this acquisition.”
Jacob Weisberg will remain editor of Slate. Weisberg said: “I couldn’t
be more excited about this move. Microsoft has been a wonderful home for
us since 1996. It’s clear, though, that The Washington Post Company is
the best place for Slate to continue to grow and develop.”..
