rah rah sis boom bah

has anyone ever been to a workshop, training session, etc. where they
didn't write stuff on those big post-it notes and then stick them all over
the wall? sometimes each person gets his or her own giant piece of paper
that they have to write stuff on. why do they always use those, even
when a blackboard is obviously available? anyone else know what i'm
talking about, or am I crazy? it just took me like ten minutes to explain
this to mike and i couldn't even find a picture of the big paper.
