+
+[FOAF][] is an [RDF][] language describing social networks and related
+information. FOAF tries to social networking available to the
+[Semantic Web][], making your identity and friendships machine
+readable. An interesting FOAF application, if you have enough
+tech-savy friends is [Foaf+SSL][]. For an intuitive explanation of
+how FOAF+SSL works, take a look at Henry Story's [paradigm shift][PS]
+post.
+
+For the curious, I've created [[my own FOAF file|foaf.rdf]]. You
+should also check out the [SIOC Project][SIOC]'s [Semantic Radar][SR]
+plugin, which notifies you of the existence of interesting RDF data as
+you browse the web (and inspired my [[rel-vcs]] plugin).

This looks like the same sort of problem that the [Semantic Radar][SR]
extension was designed to solve, except the SR extension notifies you
-about RDF files (SIOC, FOAF, DOAP, etc.). I've altered the SR
+about RDF files (SIOC, [[FOAF]], DOAP, etc.). I've altered the SR
extension to identify the `rel=vcs-*` tags.
The [[rel-vcs|rel-vcs.xpi]] extension places an icon in your Firefox
