So I’m sitting at the Old Towne Pub having a beer with my friend Joanna Young, who popped in from Scotland to say hello, and she starts telling me about how much she loves Twitter. And I’m thinking …

Twitter. That’s just what I need. It’s like IM for grown-ups. I have enough distractions without hearing about what everybody is eating for breakfast …

But then Joanna tells me Twitter is driving tons of traffic to her blog. My ears perk up. “Tell me more!” I say. So Joanna gives me the rundown on Twitter in her usual pithy and irrefutable way, so I figure I’ll give it a try.

Now I’ve been Twitting for about a week. I still haven’t figured it out — the art of conversation has always eluded me, which may seem ironic considering this is about my 600th blog post … Anyway, the first thing that blows me away about Twitter is that an entire subculture of enthusiasts, widgets, theories, blog posts, and plug-ins has mushroomed up, seemingly overnight. Anything that grows that fast in popularity among bloggers must have value. I should have spotted the opportunity earlier. (Come to think of it Joanna was trying to get me to Twit months earlier.)

Twitter fills a conversational void between blog comments and e-mail. Blog comments. Things people are saying on Twitter are not well developed ideas, like you’d hope for on a blog comment. Maybe Twitter will reduce the volume of well intended but insubstantial blog comments? Wouldn’t that be a good thing? E-mail. Sending group e-mails is clumsy and impersonal. Sending group updates on Twitter is slick and very personal.

Are you worried commercialism will overrun Twitter? That’s what happened to Facebook and it drove a lot of college kids away. As a medium, Twitter has incredible marketing potential, but is that where Twitter ought to go? Can it be used for commercial and social purposes in varying degrees and still appeal to all? I think probably so.

Do you think Twitter will lead bloggers to reduce the frequency of their blog posts? One reason I like to post daily is it makes me feel connected to other bloggers. Now I’m thinking, fewer, better, longer posts. (Maybe that’s a good idea anyway.)
