I've lost count of how many people on my Friends List have posted the following meme:
Its inevitable that as we read each other's journals we create mental pictures of each other. Post this on your own journal to find out who your friends see when they read about your life.
1) The person must be in the movies or on TV [or video games, advertising, comic books etc, ed.] (but doesn't have to be an actor/actress). The person can be specific to a role (e.g. Jennifer Elhe's Elizabeth Bennet) or just the person themself.
2) Post a picture!
Conceptually, this is a different question than "Who would play me in a movie?" -- and that in turn is different from my occasionally-revisited question, "If they made a cartoon of the Internet, who would voice your character?" It's "who do you think of as me?"
I haven't replied to any of them.
Because, well, I can't. Most of the people I know are Furries... and I picture them as their Furry Personas.
If I've met them Face to Face (f2f), I may picture them as themselves -- this seems to be directly proportional to how much f2f time I've spent with them. In some cases, I see both "fursona" and RL self simultaneously. normanrafferty has that level of quantum superposition, both Man and Rat.
pyat, on the other claw, is an unusual exception: I always picture him as his human self, even when talking to his mouse persona on FurryMuck. Perhaps it's because he posts so many pictures of himself -- and uses them as LJ icons. Perhaps it's because he's so... himself. Between his "voice" when posting and his "Fortress of Solitude" video journals, he's turned his real face into the avuncular "Geek Dad" persona that comes through in all his communiques.
For those I haven't met, don't have furry alter-egos, and seldom post pictures of themselves... usually, you wind up as your user icon in my head. Yes, thebitterguy, I see you as a South Park character with a goatee.
The people with no user icons at all? I honestly don't have mental images of you.
But in no case do I picture actors as you.
