I’m really tired of having to build a profile every time I enter a new network. It takes time, my information is largely inconsistent (i.e. email addresses, photos, links, etc), and it gives me a damn headache.
The Data Portability initiative is in the process of creating a tool that allows you to carry around a “briefcase” of personal information that you can then plug into any social outlet that you like/trust. The only thing I’m unsure of is if you can bring along your contact lists too.
