I’ve just started reading Googler Brad Fitzpatrick’s essay on the Social Graph problem and his accompanying slides. While I agree with a lot of what he says, I find that one of his big assumptions (as stated in the slides) is

some edges/nodes secret (but most public!)

This remains one of my biggest beefs with social networking - that the assumption is we want everything public. I sound unfairly old when I say this, but I’m just not comfortable with the younger generation’s tendency to put everything in the public domain. I have very separate groups of acquaintances (they’re not all “friends” in either sense) in real life and would like to maintain the same distinction online. I will put some of it in the public domain (like this blog), allow Google’s bots to crawl it and so on, but just as I have a personal blog which isn’t linked to here (or crawled by Google), I want to control access to my information, even to the extent that “most” would be “private” in the sense of being shared with certain people but not everyone. And I think this is a key feature of the endgame of social networking I discussed in an earlier post. I also wonder how Google will participate when some of the data is password protected. I think we still need the current model of providing behind the scenes authorisations for one application to access another to download key data, and I don’t want all that going through Google.

Update: looks like I’m not the only one with this concern. Although this article takes a slightly different tack, the problem it points out is essentially the same - not everyone wants all data tracked and searchable by Google. Having said that, there are ways to put up stop signs respected by the Google search bots, but not everyone knows about them and certainly not everyone would have thought it necessary before the Social Graph API came along.
