I think everyone goes through this period of e-bay discovery. At first it's all tacky and hard to use and intimidating. Then you find a few things, set up a paypal account, and suddenly you've got 30 bids going at once every day, some on sh*t you don't really even want. And then you come to your senses, use e-bay as a tool, and go outside once in awhile.
We're still waiting on my mom to reach step 3. She's one of those e-bay vultures who swoop in at the last second to grab things up. She's even got these fancy computer widgets that do it automatically now!
