The Reason to Blog

Last night, I told Nilda about my posting on the uncertainty principle. She said to me, "Are all of your posts going to be boring?" Thanks, sweetheart. You're so wonderful.

This got me thinking about the purpose of blog. Some are like online diaries (Jon Berger), some are strictly informative (Andrew), while others go for more of an audience participation angle (Bill). To me, a blog, at best, is a diary of whats interesting to the writer at the moment, and nothing more. But I still can't figure out the reason why anybody would want to keep a blog.
