How much longer can email last? How much longer before email drowns in its own sludge? Of the 130 fresh messages I woke up to this morning, 88 could be deleted without reading, being spam, familiar cranks and those tiresome group-sent "jokes" and alarums. On reading the rest, just 22 were emails that justified the sending. But just a handful were worth the reading. In another couple of hours I'll need to go through the same sorting again. And then two or three times more before day's end. How many other people are wasting their lives sorting emailed rubbish?
