That's great - I use the word in the same way. As far as I can tell, some other people don't - see the comments by RomanDavis and Blueberry that I linked to. This confusion over the meaning of the word is what I wanted to highlight.

The way that some others use the word (to mean "an agent that models itself" or "an agent that perceives itself"), either they have successfully dissolved the question of what subjective experience is, or I don't understand them correctly, or indeed different people use the word to mean different things.

And the reason I started out talking about that is that I've seen this cause confusion both on LW and elsewhere.
