More Feedback and Questions

Hello,

here is some more feedback and questions:

1.) I have been working with the spec now for a while and I first I 
could not
really use the figure "The Hydra core vocabulary" in a sensible manner
but after having understood the concepts it is very useful as a shore 
reference.

2.) In the SPEC the "supportedClasses" property defines a range 
"hydra:Class".
I wounder whether it is sensible to set a classes resource like this:
"supportedProperties": "https://api.ex.com/classes/"
which would dereference to a collection like this:

{
   "@context": "http://purl.org/hydra/core/context.jsonld",
   "@id": "https://api.ex.com/classes/",
   "@type": "Collection",
   "members": [
     {
       "@id": "person"
     },
     {
       "@id": "user"
     },
     ...
   ]
}

A hydra collection is also a hydra:Class according to the spec (although 
not explicitly stated in the figure),
so syntactically this should be correct but what about the semantics?
The reason for doing this is that I would like to have the supported 
classes being proper API resources as well.

3.) I really don't get the point about the "entrypoint" property.
What is the semantics behind it?
So far I consider it useless as it does not contribute to the URI 
resolution (which was the only thing I could think of) --
everything required for this is already specified here [1] I think.
