Plaxo - not a mouthwash (keeping your contacts, to-do and calendar in order)

Have you had e-mails from folks asking you to update your contact details by joining the hi-5 network, I have (and I daresay there are other similar offerings), usually from current and past students. What you might not know about this service is how it pollutes your privacy, here's how:

"Your friends automatically link with you when they join. They invite their friends and your close personal network grows. You can now safely meet new people through your friends network. " - Hi5 website tour of features

What this actually means is total strangers have access to your contact details, beats me why it's so popular.
Much more sensible, not to mention professional is Plaxo, not a mouthwash but a service which synchronises your contacts, to-do lists and calendar appointments with a web-based service meaning that if you're out and about mooching round the country (or world), you can readily access this information straight from a web-browser. What's more, connect your PC at home and you can automatically have that information appear on your home computer and vice versa. If that wasn't enough, make any changes and they're propogated straight away, make changes to your own contact details, and if any of your contacts are also Plaxo members, they get your updates without having to lift a finger - fantastic, if you change job say!
Doesn't this sound like a potential candidate for a corporate contacts folder which everyone has access to, and is connected via. Plaxo?
