What is needed though is a discussion about this and what the best practices in these cases should be. One option would be the opt-in for such XFN-markup but of course those links would still be available although not that easily extractable. Making it more private would probably harm the site’s usefulness. Removing them might also harm social services such as dopplr which make good use of them to find your contacts on dopplr.

So it’s many questions to be answered and I wonder what a good process might be to answer them. Surely there is the  around but of course they cannot just publish guidelines and the problem is solved. A broader discussion is needed and for a start maybe an exact description of the problem and coming from these some proposals to solve it.
