Well best you read the Data 3.0 manifesto.
The Semantics of Linked Data are very basic as per the 4 original rules
in TimBL's Linked Data meme.
Post bootstrap success RDF and SPARQL evolved from implementation
details (or suggestions) to being mandatory (an controversial
development that I don't agree with at all, even though we implement
Linked Data using RDF and SPARQL etc.. at OpenLink).

FOAF is more of an RDF showcase than a Linked Data meme showcase.
Remember, it was full of Blank Nodes. In the Linked Data realm, blank
nodes are discouraged (quite strongly).
Linked Data has made FOAF virtues clearer, and WebID may actually be the
culmination point of FOAF potential fused with Linked Data etc..

See comment above.
FOAF is not your Linked Data baseline example.
DBpedia is your Linked Data baseline example. And from there the rest of
the LOD cloud that's developed around it plus the best practices guides
for publishing Linked Data.

Governments efforts are no on par with DBpedia or the rest of the core
LOD Cloud when it comes to showcase examples of Linked Data. These
projects are still mastering many of the subtle nuances.

Neither have I .
I've found stuff serendipitously though, via the burgeoning Web of
Linked Data :-)
I don't see the Web of Linked Data as being equivalent to a Web of
Semantically Linked Data, I say this because the Semantics of Linked
Data are low fidelity at best.

You are chanelling E-A-V model here :-)

DBpedia + GoodRelations based Linked Open eCommerce style Data Spaces
are taking shape. You can FIND interesting things at:
<http://lod.openlinksw.com>, even more so when we upgrade the UI (since
nobody bothered to use the REST interfaces for the DBMS hosted faceted
navigation/pivot engine).

Linked Data and the Linked Open Data Cloud deliver on that goal.

OpenLink is about "Making Technology Work For You!". We are engaged, and
if you look closer at the LOD cloud you we see we are a little more
engaged that is typically obvious.
Just keep watching:

4. http://del.icio.us/kidehen -- lots of practical real world usage
