What about putting some more fields in 'EXTERNAL SERVICE INTEGRATION'?
In my opinion links to profiles like the ones on LinkedIn or Facebook would be great.
Also links to friendfeed, dopplr, slideshare and alternative services to the ones already available on the profile page (e.g. microblogging: identi.ca, jaiku, pownce) would be a plus. There are tons of services which could be added. Have a look at the services friendfeed is using.
What do you think?
