Usability 
Interactive transit trip planner from the Los Angeles County Metropolitan Transportation Authority. Enter your starting and ending points, time and the day of the week. (all fields default to current date and time - nice) and get a recommended routing on public transit. Locations can be entered as address, cross streets or landmarks like "LAX" or "city hall". The planner seems to work well and be easy to use. The LAMTA recommends using Opera Mini to view the site and even provides a download link!
