If a so-called productivity expert has problems with "checking email multiple times a day, of responding over and over throughout the day, deleting spam and unsubscribing from newsletters and unwanted notices, filtering out messages and notifications, deleting those dumb forwarded jokes and chain mails" then they might want to consider a career change. I've been using email for 20 years, and I only receive work-related mail (that I read at appropriate intervals to my workflow), the occasional personal email, and specific automated emails that are filtered to specific folders (where I can give them attention when I need to). I never receive chain mail or stupid jokes, because I don't deal with the type of idiots who send that kind of stuff. Those who did send me that sort of stuff were told in no uncertain terms that I'm not interested in it, and it stopped immediately (this doesn't mean I was nasty about it, though). I almost choked laughing when he said he was ditching email for Twitter. Twitter is possibly the least efficient and reliable Internet-based communications medium. And I say this as someone whose profession is software to make greater sense of that medium. Was this piece meant to be satire? It just seems ridiculous to me.
