No Blogging for Committee Members?

LibrariAnne has a detailed report on a rumor about ALSC and bloggers who are committee members not being allowed to blog. I did hear whispers about this during Midwinter, and a comment to LibrariAnne's blog confirms that ALSC is "grappling" with this issue.

So I ask you: anyone know the deal? The specifics of the guidelines? Is it just ALSC, or is YALSA doing something similar?
