		 They have sort of been trendy for half a decade or so.  I don't know when it transitions to something else, but I don't anticipate much of a regression.  Good ones at least should stick around.  Some of the smaller breweries will give up on them due to the inconsistencies of open fermentation. Also, I am generally a fan of nasty things. Sour beers, eels, and honey badgers in particular.
