Recommend me a guided FAQ system

[bloo]

I'm having trouble finding an easy to use system for creating guided FAQs, the 'troubleshooting' kind with a branching hierarchy. For example:

Are you Christian? -> Yes
-> Catholic or Protestant? -> Protestant
--> Episcopalian or Baptist? -> Episcopalian
---> Baptist Church of God or Baptist Church of the Lord? -> Baptist Church of God
----> Original or Reformed? -> Reformed
-----> Reformation of 1879 or Reformation of 1915? -> 1915
------> Die, Heretic Scum!

But imagine those as Mac, Windows, XP/Vista/7, AMD/Intel, Multi Core/Single Core, ATI/Nvidia, etc.

Keys are easy to add and revise content, affordability.
Bonus points for being able to see and manage it in a hierarchical tree view.

Note: mediawiki not really cutting it.

Oh man, I haven't even thought of UHS for years--a remnant of the pre Internet DOS days.

Depending on your application, it would probably be best to google "expert systems".

Basically, what they do is the following:

1. Come up with an initial question.
2. Register all responses, and ask the supplicants to also submit a question that distinguishes their answer from all the other possibilities.
3. Show all those questions (including "none of the above"), and redirect the people to the answer of the question they selected.

Trivial to code.

That's more of a decision tree than an expert system. There's no ruleset, for one thing.

It could be based on fault tree analysis in combination with an expert system, which is quite powerful when fed a lot of knowledge. Expensive though, I think.
