"...I can honestly say it has helped me better understand myself and others"

And that I think is the value of these typologies.

Reading the Wikipedia page about the enneagram, I see a system of nine types with three sub-types, various connections between the types, 'wings' and 'drives'.

Am I being cynical if I think that system considered in the abstract is sufficiently rich to support almost any interpretation?

Yes.

There is a lot of meat to the Enneagram. If you want to understand yourself better, it's a great thing to study -- and once you see how it applies to you, you'll see there really is something to it.
