So I put the item, a child's bed-desk combo, up on Craigslist on Sunday and started getting calls within three hours. After 9 calls, we de-listed the ad. The first (perhaps last) people are coming today (Monday). Although it's hard to tell from brief phone calls and messages, most of the respondents didn't sound sophisticated ("I'm calling about a ad I saw..."). Computer literacy is more democratic than I'd assumed. This is good.
