But this whole "e-mail is dying" argument misses the point that you don't always want "instant" and even with 24/7 attached devices, can't always have it. Ever tried instant oatmeal? Icch! Ever been slapped for e-mailing in a meeting? Ever tried to say something comprehensive on Twitter?
The point is that the "e-mail is dying" meme is just silly. What's of course happening is that modes of communication are proliferating and some of them displace e-mail in certain circumstances. Despite Facebook, Twitter and Wave, e-mail will be with us for a very long time.
And there's still lots of room for innovation around e-mail. GMail is of course the best current example. Whenever I go back to using e-mail on Outlook, I do indeed feel like I'm in the last century. The product is slow. It crashes on me frequently, probably because I've got a few add-ons (Salesforce, Linkedin, Skype). It uses an old database form, allowing messages to be in only one place at a time via folders instead of infinite places via tags. Threading doesn't include outgoing conversations. Search is abysmal. When I use GMail, it's a joy. Spam is mostly killed before it comes to me, thanks to Google's servers. Conversations are threaded beautifully. The product gets continual tweaks, many of which I can toggle on and off via the "labs" function and all of which work perfectly, with no effect on performance. And there's even a great GMail app for my BlackBerry, though it doesn't offer the instant "push" of normal BlackBerry e-mail. I have to wait for it. But when I do, I can search for any e-mail in my database, I get to see conversations threaded, and the product just works. And I can take a few breaths before I have to respond. Someday, perhaps, the forced asychonysity of e-mail will be appreciated again for what it is after all the hyped up alternatives begin to taste like too much cotton candy.
