Following up on one of the suggestions I received last weekend at the Bike Summit, Los Angeles Streetsblog has created a twitter account named "labikes" which will inform cyclists of action alerts, public meetings, and action alerts to help the community get more involved with issues as they come up.  Unlike Streetsblog or other bike tweets, these will be "just the facts" to connect people to the meetings and issues.  For example, labikes just tweeted:

LABAC Planning SubCommittee – 2:00 P.M. Today at Caltrans Building
Agenda: BMP, Expo Path, Bike Parking, and NBC Universal

If I can find a place online which has the meeting agenda or a direct link to an action alert, it will be provided in the tweet.  You can sign up to receive our twitter feed at twitter.com or sign up for the RSS feed here.
