However, it does seem (and the article doesn't stress this but I think it's important) that there are simply TOO MANY different channels of communication. Figuring out which channel that communication came through on, in order to find it, is a problem. Since getting rid of email seems impractical, as does getting rid of face-to-face, IM seems like the best one to drop.
But again, who care what I think? No one. In this case, I try not even to let me care, and save my energy for battles I might possibly win.
