what are you adding?

It keeps occurring to me to post in various mailing lists

"Hey have you considered such-and-such?"

But it also occurs to me to stop myself. Is it really going to add
much? Perhaps not unless I actually have time to follow through and
actually implement the thing in question.

I don't see the point in talking in that way, if I'm just doing it to
hear myself talk. That's what blogs are for :)
