If you read Marketing Pilgrim, or if you read online marketing blogs, you’ve probably heard of Twitter. It’s the rage at tech conferences and in certain communities. Outside of these circles, almost no one has heard of it. But while it may not have reached critical mass, the growth is pretty impressive.
I’ve noticed that people either haven’t heard of Twitter, have a mad crush on it, or HATE it. I asked a room full of paid search managers if they tweet, and one did. Out of the total number of people I work with (most of us do SEO or PPC) my guess is there are about 5 people on Twitter.
