Via ABO's twitter feed, I learned that finally the Broadway Shuttle is on NextBus. In a test run yesterday, I noticed similar problems with timing I found when NextBus first arrived, but those seem to have since worked themselves out, so I'm hopeful.
I'm amazed this service didn't launch with NextBus. A good deal of the FreeB's utility derives from the fact that one can take it on short hops during a lunch hour to save time and increase the range of accessible places. It helps not to have to wait 10 minutes on the front end of the trip.
Overall I love the Broadway Shuttle, and think it is a great addition to both AC Transit and downtown Oakland. I've been taking it once or twice a week since service began, and it appears to be well used. I have further thoughts that I've been meaning to write for months, which I hope to get to soon. Stay tuned.
