What are lawyers doing with Twitter anyhow?

Curious about that new-fangled thing called "Twitter."  Are you lost when colleagues discuss great "tweets" they read?  Then visit kevin.lexblog.com to see some examples of what lawyers are doing with Twitter.  Once you know how this social media tool is being used, it's a lot easier to decide if you want to incorporate it into your professional activities.  I was on the fence about Twitter for quite some time, but I like the idea of using Twitter as a micro-blogging tool to supplement blog posts, particularly when the information may not rise to the level of something I want to cover in a fully formatted blog post.
