I thought- if Spock knows everything about my Social (and real) friends, and puts to their profiles not only tags and photos but also their Web references- so why Spock could not allow us SEARCHING through our Trust Network (or Global Network) for an URL that could be in some way related to a person on Spock?
an example: my friend Michael has a personal web site gfdsa.org, and let's assume (just for example) that I forgot that gfdsa.org is a Web Site of Michael but I need urgently to disvover it and (for example) I can not find the owner-related info on the Web Site. This happens sometimes with Blogs- there is no reference to who's the Blogger but it could be important to know :)
So, I'd love to go to Spock (today) or to use its API from any 3-rd party application (the future), and since gfdsa.org is registered as Web Reference for Michael's profile on Spock and confirmed by the another Spock Nodes, I'd love to be able asking Spock a question like "Who from [my] Network has a Web Site starting with gfdsa.org in the Web Reference list". This could be a complete URL, or a first level domain data only etc- the details are not important now.
I think with this feature Spock would really become the greatest ever People Search Engine, since if would allow us also to DISCOVER the People owned Web Resources like the Blog, a work site, etc. (if those are claimed by res. owner, or found by Spock Robot and confirmed, or added by some Spock Node for another node)
P.S. I understand that with such kind of URL Search feature, if one asks for "linkedin.com" or "facebook.com" he would get the whole Spock or half of it- it's OK for me, anyway Spock would just list the people's profiles and the number of it.
