Solving Real Problems using Linked Data: InterWeb scale Verifiable Identity via WebID

All,

Here are links to recent G+ posts that showcase use of URIs, LinkedData, 
and WebID applied the thorny issue of verifiable identity at InterWeb scale:

1. http://goo.gl/AcYWQ -- using Facebook as an Identity Provider (IdP) 
for the WebID verification protocol
2. http://goo.gl/ouXeF -- ditto using LinkedIn
3. http://goo.gl/9jjxG -- ditto using WordPress and other AtomPub 
compliant blog platforms
4. http://goo.gl/FFsjv -- ditto using Twitter.

What does this all mean?
Anyone with a Facebook, Twitter, LinkedIn, or Blog Platform account can 
now do the following with ease:

1. generate a self signed X.509 certificate with a WebID watermark
2. persist certificate to a keystore/keychain provided by host operating 
system of browser
3. persist certificate fingerprint (MD5 of SHA1) to Web data spaces such 
as: Facebook, Twitter, LinkedIn, Blogs etc..
4. as part of the WebID verification (authentication) protocol, lookup 
the fingerprints in the aforementioned data spaces.

As a result of the above, it becomes much easier to achieve a global 
scale Read-Write Web since WebID granularity works for:

1. access control lists (acls)
2. signed emails via s/mime
3. semantically enhanced notification services that only require a WebID 
e.g., befriending, resource share notifications etc..
