I guess it's about having someone who's going to stumble over the details that many of us would miss (because we have so much knowledge).

I watched a bit of their twitter demo and it was actually pretty entertaining. During the account creation process it suggested potential usernames like 'pam18773642' and she said, "how the hell would I ever remember all those numbers?" Once she'd picked a name it wasn't obvious that it was valid.

I agree, you need to know who your target audience are and test for them. Still, it's enlightening to see the web through the eyes of someone with very little experience.
