desktop search in kde 4.0 :-)
http://nepomuk.kde.org

(and is also a sweo use case now)

negative view:
in the public - probably none.
Most articles in it magazines on the topic start with "the currently 
non-existant semantic web is still an academic endeavour, but...."
and many people use the word "semantic" but don't write it RDF...

(you know the positive views)

good awareness barometer,
but there are none to few applications that actually USE this data.
(mobile dbpedia one of them)

enough eggs and chicken,
but nobody eats them or releases egg-based food.
>

the Role of W3C is a problem, as the doctrine to "not release 
ontologies" is tricky.
standardization bodies usually also do the ontologies as such, providing 
a registry and model to author them (tools, communities, etc). There are 
some semi-official ontologies such as w3c-vcard or w3c-geo, but they 
were published and then left desolated, there is no formal body 
nurturing them.
hence, with the standardization of good ontologies, the semantic web 
will benefit

second change of the role of w3c is "now we do hire marketing"
in 2006 (when I joined SWEO), w3c position was more like "no money 
invested into marketing, we invest into standardizing and technical 
staff". Position changed, which I deem good.

sure, #swig lives on.

add the "linking open data community"

a little. the use cases probably help.

Drupal.

nepomuk.kde.org , click on "user"

(if mom uses Linux)

named graphs were also the past.
you notice these http:// uris in the namespaces? .... well, there has to 
be some RDF there....

NO.
XML serialization is not really XSLT friendls,
schemas have problems when it comes to lists and embedding 
HTML/RDF/XML/text into each other.
basic parts of RDF are missing, such as connecting a document to the 
metadata about the document (what triple do you use for connecting the 
two uris? seeAlso?)

they should all use RDF.

make google use semantic web.
the easiest way: do a company, get bought by google, smuggle semweb into 
google this way. (the perfect businessplan and way-to-success (tm))

when the main way to import appointments and contact information from a 
website inty my calendar/addressbook is using RDF. and is a natural 
thing to do for firefox/internetexplorer.
