I'd love to know if labanotation has actually been effective in dance. It might work for choreographed works, but I feel like it might fail for a newer person relying on it over practice.
Yes, it works great and not difficult to read. There are limitations, mostly because of symbol overload when expressing more complex movement. Ballet is simple to read because ballet consists of mostly well-defined upright movement. Modern dance, of which ballet is a subset, has a lot of floor work. That becomes difficult to express.

The system encompasses the entire body up to fingertips.
Any social dancers on HN?
