Sometimes I see something I am impassioned about and want to reply. But when I write a thing, before I press toot, I ask three questions.

-- Who wrote what I am replying to?
-- Are they an expert in the subject? If so, what am I going to contribute that they don't already know? (Nothing? Then cancel, but if you still feel strongly about it, post it on your own timeline. Don't @ them, they're busy.)
-- Has someone else replying already said what I did? (If so, back off... And don't post "Me too!")

If I can do this, I know more guys can, too. Don't be a reply guy.
