Something in the air, apparently

Rico says that, according to his ladyfriend, who keeps up on such things, the Angioma Alliance reports that a majority of people with brain bleeds (like Rico) have them in the fall. (His was on 29 November 2006.)
Now he notes, upon clicking through the list of blogs in his sidebar, that two of his favorites, Pete Puebla's blog of his tour in Iraq and Bated Breath, both closed up shop on 11 December 2006.
No apparent connection, but an interesting coincidence...
