Take a look at this progression:
At some point you had to have all of these things if you wanted to be a respectable denizen of the Web. In other words, at some point all of these things were in a fad stage. Some of them, like the blink tag, went over the top and became a target of ridicule. Others, like the blog, have matured into valuable tools when used properly.
Fads tickle my cynicism bone, so I tend to resist them. I’m still in the “wait and see” mode with regard to Twitter. Even though I have a Twitter account, I haven’t done anything with it since I created the account. Same goes for my Facebook page.
My point: Don’t worry if you don’t tweat. There’s nothing wrong with waiting on the sidelines until the playing field makes more sense.
On a side note, my local TV news stations have discovered online polls to try and get people to visit their Web sites. I remember ten years ago, when I was an online news editor for a local newspaper, we used to do those silly polls that were absolutely meaningless. TV is on the same glide path as newspapers.
