I notice that a few of people, particularly @davewiner like to go on multi twitting diatribes. Is this a proper use of the Twitter medium? Is it valuable to use a half dozen micro blog entries instead of a single entry that links to a full blog post.  Or possibly a more refined message that gets right to the point in 140 characters or less.  Now I certainly have nothing against Dave or others that twit in this manner, but it is not common amongst the few people I follow. Certainly Twitter was designed to be a status mechanism and this fact is why I see that it isn’t meant for an extended conversation.
Maybe Twitter is different now than when it started.  But I think the 140 limit is important to get users to commit to a single thought that is valuable to their followers.
