According to this Wall Street Journal article it is. It says people are becoming so used to communicating through Twitter and FaceBook (soon to be joined by Google Wave), but I think it is like the proverbial "jumping the gun". Of course I’m not denying that you can communicate faster using Twitter and FaceBook and some things you don’t even have to communicate through emails because you have already posted an update, there is nothing like "we’re always connected". I, for example, am not. Today I haven’t checked my Twitter and FaceBook streams simply because I was too busy working and replying to important email messages. If you are always connected one thing or the other keeps disturbing you and you cannot focus on work. It’s BS when people say they’re more productive when they are constantly checking Twitter and FaceBook updates and posting responses.
Of course you can get constant email updates if you’re using some sort of notifier (I sometimes use Gmail notifier or GoogleTalk to get instant email notifications) but it’s not like Twitter and FaceBook. When I’m in work mode and when I’m waiting for client response I’m not interested in knowing what sort of coffee you’re having or what’s the latest political gaffe the government is committing (I’m not saying these things are unimportant).
People immediately started discounting blogs when Twitter and FaceBook caught on but such a trend was obvious. It is so easy to post small messages and amusing links on social networking websites but writing a blog post on a continuous basis is difficult. The popularity of blogs hasn’t diminished, it’s just that fewer people are trying their hands at blogging because it’s easier to share thoughts on Twitter and FaceBook.
The problem with Twitter and FaceBook is that they are not as personal as an email. Things that you used to share with a select few are shared by everybody following you or befreinding you unless you take extra pains to exclude some people. In fact, this is the big difference in email and social networking apps: in email you have to include people if you want to communicate with them. On Twitter and FaceBook you have to exclude them — physically — if you don’t want to communicate with them. They’re more public. Email is private, and it is not going to go away easily. May be the form will change, but it’s here to stay for at least a few more years.
