It never caught on, possibly because the mental model required for successfully hacking with "event streams" and "behaviors" is decidedly a functional one, and those concepts are quite abstract to begin with (more so than objects and prototypes). Also, studying the implementation is not for the faint of heart. On top of that, I don't think any big names got behind it and there wasn't exactly a marketing campaign. Ahead of its time? Definitely. And it's probably still worth looking into as an alternative when trying to choose among the various reactive libraries that have popped up in the last year or so.
