Thanks for the pointer.  This argument makes sense to me.

Would I be right to say these are proposals, rather than, in use?  For
example : ( https://w3id.org/verb# ) is a 404.

If there's no currently reusable equivalent of http://ontologi.es/like#likes
in AS2 or another vocab, I think I'll stick to that until an alternative
presents itself.

The former is already in use by openlink, so I think it makes sense to
reuse that, at this point in time.

Later on I can think about embedding a Like notification in an activity
stream, but I just wanted to solve this part first.
