On: Facebook Is Kinda OK but Largely Overrated : Matt's Homepage

Weren't business professionals Rolodex's target audience as well?

i don't know. I'm not old enough to remember. I just equated a rolodex to an ancient address book... anyways my point is that plaxo just doesn't have the coolness factor that facebook for has personal use, though you're free to disagree

Oh, I don't know anything about Plaxo, other than what they do. Never had any use for it.
