Sure it does. as:follows points at the collection of people you follow. 
as:followers points at the collection of people who follow you. These 
would be defined as owl:functionalProperty(?) - there may only be one of 
them.

Maybe it doesn't mean what perfectly idiomatic RDF would say, but it is 
certainly workable and even practical. It mirrors what AS1 deployments do.

Hydra's collection design is interesting, though I'm concerned about 
some aspects of it: How do I find the collection which contains my 
followers for example?

And is there any tooling which is capable of understanding the semantics 
of a Hydra collection?

I'm somewhat concerned that Hydra's collections may be this lovely, 
really clean design in theory and this complex, difficult to implement 
thing in practice.
