My experience is that it comes down to groups of people, who's in charge, and how the group of individuals handle the "organizational culture" of the community. A common problem is that it's (like I hypothesized for Caitlin) a revolving door. You can't really build something stable and innovative if most people are going to get bored with studying all the weird symbols and hand gestures. Even an Order that wanted to slowly build something amazing (though I personally think that the established high magick traditions do tend to be regressive and conservative in order to keep their traditions unadulterated), there is still the problem that very few human beings stick with anything for ten years.
(Quick note: I have a ton of respect for Thelema and O.T.O., I'm not questioning their aims or methods--merely delineating the challenges.)

To actually hold beliefs and also create new things, simultaneously, it (in my humble and often presumptious opinion)can take many years. Yet we rarely see that. To me, the most vital work ends up being single individuals who do a whole lot of occult tourism and then eventually manage to articulate what they've learned or uncovered. I mean, Jack Parsons is no joke, but he didn't lead well or play well with others.

When creative madpeople are the only ones that can do it right and it needs intense organizational skills and detail-oriented labor-intensive work (not even mentioning how it takes a whole lot of time and money), it's a curious balance and it, far too often, becomes impractical. So, yes, I confess to being grounded in my own experience and knowledge and I freely admit that I might be dead wrong, but I certainly share the curiosity and agree that, for those of us who truly understand these things, the community of The Immaculate Order of the Falling Sky may actually be about as good as it gets.
