Keith has a point (re. IRC discussion) that the meaning of "@nick" on
twitter may not necessarily mean that one message is in response to
another.

That is how twitter home page interprets it when saying "in response
to " and linking to the last message written by that person. But
it is not necessarily what that person mean (determining what someone
was thinking about may be a difficult task anyway :).

There are different options depending on how much we can derive from a
twitter message and how deep into detail we want to do. You could:

a) just say "person X mentioned person Y in his message (A)" - but
would probably need a new (quite specific?) property for that.
b) say that "person X replied to person Y in his message (A)" without
specifying a particular message by Y that a reply is to. you could
model this case similar are you would model Usenet or email messages -
by Y being a recipient of a message.
c) say that "person X in his message (A) replied to person's Y last
message (B)" - in this case you can use sioc:has_reply.
... there can be more ways to look at it ...

Depends on what you want to use this information for.

same with RDF embedded in person's homepage, of course.

Another idea:

Extract hyperlinks from tweet text and express them as sioc:links_to:

Since twitter usually shortens URL, such RDF-generation service could
resolve these URLs to real, long URLs (optionally get some
meta-information, e.g., page title) and use these in sioc:links_to.
