The latter half of that is true, isn't it? And yet.

This is why you can't treat that type of statement as purely factual: so long as you're sharing a world with it, it's of a quine-like type which is always performative to speak, in a way, because how much people believe it on various levels (and thereby decide (or unconsciously "decide") things like "why should I bother to connect to these people when they won't even sign up for a free Facebook account to make it easier for me, since everyone knows that's just what you do") influences how true it is in a much stronger way than is the case for most objective statements.

In light of that, I wonder whether my having said the above is good or bad? Hard to tell.
