SOCIAL NETWORKING: Google Social Graph API

Sometimes the plot about I am going to write in a daily basis at this blog comes from what I have read that same day, ..sometimes the idea comes just because I feel like talking about it, ..sometimes because someone asked me about a topic and want to share the answer with you all ..and this is the case of today. I was asked about public information of people relationships on the web. Is there such a thing??. Well, absolutely, actually more than you may think (twitter, facebook, digg, ....etc. stores this information as public, and even more this information can easily accessed if declared by XFN and FOAF markup.

Google is working, in one of their labs, in a Social Graph API which access to many public sites looking for:

• All public URLs that belong to you and are interconnected. This could be your blog (a1), your LiveJournal page (a2), and your Twitter account (a3).
• Publicly declared connections between people. For example, a1 may link to b's blog while a1 and c link to each other.

...How this API may help us??. Well there can be many funtionality which bombs my mind, for example:

• Getting to know all your friends to check the availabity to contact you for a job offer or just for a deal.
• Getting to know all your public URLs may be interesting to know what you are interested in, and so what to sell you (hmmm...interesting tool for one of the main money incoming sources for searchers!!)
• If you sign in a new website, ..why do you have to upload again your profile info, picture, CV...., why are not just asked you to get all that info from other sources as facebook, Flickr, .... A nice development is being done by Glenn Jones with Ident Engine.
