Personally I read messages, keep them only long enough to take action (when that's necessary) and then delete them. I don't want my brain cluttered by dozens/hundreds/thousands of ancient, no-longer-relevant messages. Furthermore, when the blackshirts come to get you, it's your own old messages they'll use to hang you. Get rid of them, I say.
