Twitter seems slightly bird-brained

Okay, I confess. I don't really get it.
I saw the video, I read the LJ article, and I do see some applications for microblogging. The way the young adult librarians are using the system, the way the libraries are announcing new materials--that seems pretty cool. I can even see how my husband, the youth minister, could use it to remain connected to his youth, and even create excitement about upcoming events if he twittered about the preparations that he's doing.
For me, though? Not sold. It seems to me that all of those little bits of time that are used to update people on what you're doing to be more profitably spent in actually doing (working, anyone?). Call me old fashioned, but I'm a big believer that little bits of time add up. For instance, I may have a minute or two that I use to run a few patches through the sewing machine before I leave for work. Before very long, I have enough put together for a quilt. When you see something that major come together out of little bits of time used wisely, it's pretty impressive.
But all those little bits of time spent informing people about things they don't really need to know?
Okay. So we want to remain connected. If I followed my husband's twitter all day long, I'd already know what his day was like, right? So what would we have to talk about when we sit down to dinner?
Maybe I'm just a privacy junkie. I don't think people need to be constantly connected to me, and I don't think that stopping to tweet about taking out the laundry, putting dishes away, shelving books, or taking a break is a good use of my time. Instead of a smooth flow, a focus on the next task at hand, I'd be thinking "What do I say? Oh, don't forget to tweet about this."
Waste of time.
