So, Fred Wilson organized Lyrics of the Day (@lotd) on twitter. Twitters can post a short lyric that they think everyone will enjoy and direct it to @lotd. All that are following @lotd will see all lyrics posted to @lotd. This is both entertaining and smart.
You can apply this concept to events, conferences, new album releases, product launches, comments from your blog, whatever. If your audience is on twitter and is talking about your stuff, do your community a favor and streamline the communication by organizing the topic at hand and thus facilitating more talk.
