I am user of Twitter.
For those of you unfamiliar with Twitter, you can think of it as a combination of blogging and instant messaging. Each post or tweet is limited to 140 characters so you can send tweets by text message. Like most social media, it is cheap (free and currently free of advertising) and very easy to use (there are only a few buttons).
Steve Matthews wrote a great post on an intro to Lawyer Marketing with Twitter. Kevin O'Keefe followed that up with his own perspective and success stories in Lawyer Marketing with Twitter Has Arrived.
Like both Steve and Kevin, I've had a few Twitter moments and find it useful to engage people through this communications platform. In this era of new ways to communicate beyond email, Twitter is a great avenue to communicate and share information.
Rather than duplicating what Steve and Kevin said about Twitter (you should go read both stories), I have two additional features that I like about Twitter.
First, it is very compatible with other platforms. The flow of tweets is available through RSS. For example, Twitter ties into Facebook and updates my Facebook status. I have a Twitter widget on this blog showing my most recent tweets. I also have a Twitter widget running on my intranet page.
Second, tweets are indexed and returned by internet searches. All of that good stuff in my tweets, gets returned in a Google search, just like posts on this blog. You are sharing beyond the Twitter universe.
