stupid questions

Hello everyone:

I know maybe I'm asking stupid questions, but I really need your help.

I was trying to find some websites help me recognize the ability of RDF and TMs
on seamless knowledge [1] , Semantic Web, knowledge representation, 
knowledge organization or information retrieval.

I noticed that there are some websites based on Topic Maps organizing
the resources,
such as "Omnigator" [2] and "NZETC" [3] .
Are there any websites based on RDF organizing the resources too?
Any digital libraries or portals?

Another question. Are there any "web search engines" making for
searching Topic Map documents?
Like "Swoogle" [4] search RDF documents.

Any websites you're impressed on implementing this two technologies
are appreciated.

The last question is:
I know we can define semantic relationships between topics/resources
with TMs(or RDF).
But as a user, I cannot realize the significant differences between the websites
have been built with TMs(or RDF)  and those have not. 
I cannot perceive their "power" of  knowledge representation or
knowledge organization
because we can also represent semantic relationships without using TMs(or RDF).
( I did not mean to offend anyone.)
Could anyone tell me what's the advantage for a website(or digital
library, portal...)
building with TMs(or RDF) ?  (especially the advantage which couldn't
be accomplished
without TMs [or RDF] )

Thanks in advance and best regards,

M-L.
