Slam the Boards!

I love the idea of having specific days where Librarians go and answer questions at online Answer Boards. I do have 2 problems with this however. Do we really need days in which to promote the library and get librarians involved? It would be much better practice to have librarians checking answer boards regularly and getting involved.
My other problem is that people arent't aware that librarians are a direct source for information and the answering of their questions. I am being quite hypocritical here because before working in a public library i wasn't aware of the resources and knowledge that librarians and the services had to offer.
I see posting in Answer Boards a great way to promote the library service and the knowledge of librarians, it just seems frustrating that every post is only reaching a small minority.
I would love to see people just coming straight to their local librarian and asking their questions without having to resort to Answer Boards (and from experience i know answer boards are a last resort when you think you have exhausted all of the resources available to you).
It seems so disappointing to me that librarians have to go out and actively find questions to answer.
