I for instance do not see a problem with people replying to ideas-wanted when
they have something valuable to say. But if the topic has drifted away from
the original idea (which often happens) it would be a good idea to think a
moment before hitting "enter" on a group to reply to. (Hey, I didn't code that
for nothing! Typing "bs" there is easy, don't make me make it a default for
mortals. )
