I wonder if there's any chance that Advogato might get an option to remove the FOAF data export from one's profile?
At the moment, the file exported through this site is the only FOAF file about me that I'm aware of. It gives the impression that I know about a dozen people; all but two of these are people that I don't know at all. I know some of their code, and I have a sense of their current or former position within a particular field, on the basis of which I certified them -- but I don't "know" them, and I wouldn't have said I "knew" them eight years ago when I actually certified most of them either.
This FOAF file is completely misleading, I don't agree with it, I didn't authorise it and I don't want it -- and since it isn't possible to un-certify people on Advogato, there seems to be absolutely nothing I can do about it. (Not that I have any wish to un-certify anyone; I have no problem with the certifications themselves. I just don't want them presented as something they are not.)
I don't feel it bodes well for the semantic web, when even at this early stage almost all of the "knowledge" in it about me is wrong.
