In reply to:

JUST IN CASE I MAKE A MISTAKE IN THIS POST ABOUT BASEBALL LORE THAT MIGHT TRIGGER OFF A FLURRY OF POSTS ON THAT SPORT I'M DECLARING A BASEBALL YART...

Whitman, I think (unless I am misreading your post) that you have extended (perhaps erroneously) the generally accepted usage of YART, which in the past has been applied in the main to warn about warmed over topics. while the discussion of YARTs itself certainly qualifies as a YART, and while there has (on rare occasion) appeared the odd self-YART, I don't think that we can expect folks to predict YARTish digressions when they make a post.

or did I just obviousize your point?

(no, having just reread what I've typed, I don't think that would properly characterize what I've done....)
