Has anyone considered the potential of having a Twitter ID field in the profile (or fields for other similar microblogging/social networking services) so that those who want to can advertise their other profiles, allowing people to network with people in their field?
The particular value of this, I feel, is more in Stack Exchange sites where the sites are often much more specialised and you are participating in a small community where it's useful to keep tabs on who's doing what.
