Web 2.0 Service: Final Linksource

We all now have 5 email addresses, 20 memberships to various social networks, and not enough time on our hands. With the advent of OpenID, they tried to confine multiple username/passwords to one login; however, the issue of net anonymity has prevented from widespread use. Likewise, social networks have been created to incorporate other social networks, but it is just as easy to umbrella these umbrella social networks and create more work for the user.

There is a simultaneous draw to provide relevant net presence but also keep an anonymity. A service to provide "linksources" would be the solution - a basic, though final profile to link social network profiles, blogs, resumes, portfolios, etc. Certain options could make information only accessible to friends and contacts, and further checks could divide sections up for business and play. I must stress that this will not be another social network (or else it will be prone to being added), but a list of links linking to all subscribed social networks.

Other ideas:
- incorporate OpenID
- create business cards with USB contacts that automatically link to site when plugged in
- visual links (thumbnails for all the links) on profile site
