I still don't grasp the point of Twitter. Although I've signed up and have begun "following" a few people (including Lance Armstrong and my brother Glenn), I've received no notices of anyone's posts. All I've received are some e-mail messages informing me that people have begun "following" me. Why am I not receiving e-mail messages when people post to their Twitter accounts? Does it work only with cellphones? If so, then it's not much use to me, since I refuse to be leashed. I have a question for those who are "following" me. Are my posts getting through to you? If so, in what form? Explain to me how it works. Here is my Twitter page.
