As of right now it is a pilot program, that keeps getting extended month after month. I follow this account and its great to see what they are doing. Closer to home, Metro is trying, alerts get out about reroutes and issues, but what if they did the same thing Translink is doing? Although, I have reason to suspect if Metro had the level of activity as Translink, a few STB bloggers will still find something wrong with it. I think its a great idea, as I have mentioned before, this is a platform that people use, and its great to see Translink take it to the next level.
You can read about the project, submit your feedback, and look at stats of the first month of the project on their blog.
Update: This project is now permanent!
