Totally agree with Jennifer about blogging.. she says:

One of the points I see in blogging is to try to reach people, and to get them thinking and talking. And debating. Or arguing. I don't feel the need to reach thousands or millions (or even tens) of people. If I know I've touched just one person by something I've said, or introduced new possibilities to another, or made a connection with a delightful, intelligent, creative, or fascinating person whom without the Web I never would have heard of...It's worth it.
