@trwnh @julian @silverpill I think the question here is "does a thread actually have any distinct properties of its own?"

Maybe a title, but that can also be inherited from either the first or most recent post. Many threaded discussion systems don't have thread objects at all, of course (email is perhaps the canonical example)

So I lean towards the idea that you should just redirect to the first thread in the post, and place the context (which when becomes just a collection of in-thread posts; an implementation detail) at another URL where it mostly becomes invisible to users.

And I think that's better, especially because having significant semantics on collections starts getting confusing when e.g. you have collection pages flying around

Really I think most types which can be represented directly as a collection (e.g. image galleries) are best represented as an object that possess a collection, though not everyone might agree
