I respectfully disagree. While I confess that I am an ubernerd (in addition to other fine qualities such as being a well-known chocoholic), I see plenty of people on twitter who are not techie at all. I follow a few quilters, for example; one of them has a blog with neat how-to videos. And for some reason a lot of real-estate people from Phoenix are on twitter (they follow me, I'm not too interested in them). I realize that they can be invisible to techies. Like LinkedIn: you only see the people on twitter who you follow personally, so there's a sense that everyone is like yourself. But that's not the case.
