Not to mention the people that never read the whole message if it is more than two sentences. I can’t count how often I have seen some ‘urgent production’ issue email thread with like fifty people and fifty emails and the stupid answer was in the logs in the very first email all along.
Checking email too often is a productivity killing habit.
However, the worst, most common, problem with email is disorganization. It takes a great deal of effort to organize received emails so they are appropriately handled.
I do not miss the days where I’d spend an hour every weekend filing my inbox.
