Check out Isobel Wren. She doesn't just talk to people for the sake of talking; she actually has interesting things to say. She's a really sweet person, and she's so "real" -- like she could really be the girl next door, not just somebody who's cultivating the "girl next door" image. And she's intelligent enough that you can tell she's real -- not just a cyborg that's programmed to be friendly and responsive. Go to
her profile, click on the "Statistics" tab, and then click on "Find all posts by IsobelWren", and you'll see what I mean.
