Well, I hardly think most of the data is sensitive. Probably only a few %. But the general point is correct. To get an idea of what information might be sensitive you might want to look a a few surname lists and see how many of them are open (white) vs one of the privacy settings (colored). And even most of the material on a privacy protected profile isn't particularly personal. That is, the material is readily available I suspect the real question is how much slower or resource hungry it would be to upgrade security here. Now it might be possible to access through a secure server, but it wouldn't protect the data itself. I don't know what protections there are on the data here, and it wouldn't be wise to discuss it here if I did, but perhaps Chris Witten will come along and discuss whatever is appropriate to discuss.
