Jim Baen's Universe is closing in April 2010, according to an article on their website. (Source: Ralan.com) This is a major loss for speculative fiction fans and writers. Here is JBU's announcement, written by Eric Flynt, General Editor of JBU and noted author, who recently suffered triple bypass surgery.

I noted on SF Scope that Farrago's Wainscot is closing, too.
