Yes, I think it does matter. And no, although it won’t last, not like it is now, it is the beginning of something that will last, but will be changing a lot. I could say the same about personal computing, the Web, and blogging.

Twitter is all the rage because it hit fertile ground. People like it, people use it, and because what it does catches us. The key to it is something related to publishing and broadcasting. It’s why I like writing this blog, why you like writing your blog, and why both of us read each other’s.

It’s related to instincts deeply embedded in our human nature.

The first of these is expression. When nothing else was possible, people drew on cave walls. That was about expression. So is telling stories, reciting  poems, and singing songs. It’s in our nature. We crave expression.

The second is curiosity. We want to see the pictures, hear the stories, know what’s up, and what’s going on.

And then, beyond these two basic instincts, there’s how much we like gathering, and shows, entertainment, and keeping up with each other.

All of which happens on Twitter. It’s not email, it’s not blogging, it’s publishing in 140-character pieces. Do it well and you have more people reading what you publish. Do it poorly and you have nobody reading what you publish. Make it interesting, informative, or funny and it’s good to do and people will follow. Use it to sell stuff or whine or share trivial life details and people will stop following. Use it to push sales talk at people and they will stop following.

Which–the click to follow or not–is the clincher, in my opinion, that makes Twitter more significant. I’ve seen some very interesting musings on Twitter’s future, such as Jeff Sexton’s piece asking is Twitter is digging its own ditch?  He says some of the Web’s bright and shiny new things (he mentions Digg and Technorati) burst on the scene, become popular, and then got manipulated, declined. The classic pattern is email with spam now killing it. He asks whether that might happen to Twitter.

And I think not. Because of both sides of the coin: the instinctive allure of posting like this, and reading the good posts, which is one side; and the ability to click and unfollow people, which is the other.

So please, follow me on Twitter: click here.
