indeed they are lots of small examples (taken from the list or 
experiments) but they show what can be done

if they crash (no sure what you mean there) it's most likely due to 
fonts you don't have on your machine

a lot has been published in articles in user group journals or for 
meetings, there is a font manual that you can buy for nominal costs, 
there are some manuals on the website and an extended version of the 
more technical one that hardly anyone needs will end up in the 
distribution some day soon, there are examples on stack exchange, in the 
mail archive an don the wiki ... a lot of this depends on voluntary work 
so you can hardly complain about it .. anyone is free to provide more 
documentation and share experiences


btw, if you want to roll out your own features as in extensions-001 then 
you also need to know what the font provides (or lacks) .. open type 
fonts can be pretty complex and there is no consistency in how certain 
features are implemented
