Kent Newsome brings up a concern with Twitter that is pervasive in the blogosphere. Many conversations are one-way. He's also suggested that he'll unsub any twits that don't appear to be listening to him. I ask why this isn't happening in the blogosphere? Why do people persistently link to a-listers, who thru no fault of their own, don't have the time to respond to everybody. The blogosphere and twitter is about two-way conversations. Persistently linking to the same a-lister for that once-a-month or two return link is not a conversation. Kent has some great advice. Start talking with people that are listening to you.
