I read a couple of articles in the WSJ yesterday which have given me pause. The articles were dealing with email's role in modern business, and the rapidly changing modes of inter- and intra-office communication.
New apps are fun, and new gadgets a blast. What I read described a world of communication and decision making that goes beyond hip to paradigmatic. You are working on a project with 20 colleagues in (or not in) your office. You need to act on your part of the project quickly, and want feedback. If you send an email to the entire group you put yourself and the timing of your actions at the mercy of the other's email filters and schedules.
You are part of a "beyond hip" company, and have bought into an app like Slack. You put your request for feedback out to your Slack team (which is the company culture) and hear back immediately from colleagues. You didn't need to hear from everyone. You don't. But you do have your feedback, and can proceed. Job done.
What does this have to do with websites?
I forsee a growing array of websites that attempt to enter into this new world of non-email collaboration. The dynamic is here. Google Apps, Slack, Facebook, Twitter and others do not need websites to function efficiently. Right now websites offer "Call to Action" buttons and portals for interaction. Will they further evolve in ways that further replace email?
Email will be around for a while, but it sure seems as if its days—and uses—are numbered.
