Perhaps putting these fields and the phone number onto the main account page would be better UI? It will also bring forward the statement about IndieAuth (I like the description by the way), which will help to make other posting interfaces and applications more apparent--particularly in the early Beta days when they're so limited.
Additionally adding a field for Instagram (wrapped with rel-me) will also let users potentially use https:/
Similarly a swarm/foursquare field for aaronpk's ownyourswarm would be useful, though he may have to do some tweaking to get it to work with micro.blog as it's relatively new.
Other than that I think I mentioned most of the other commonly used IndieAuth data pieces above.
