Daniel/LOD Community, I've seen this as a problem myself, not only finding SPARQL endpoints for datasets, but finding relevant datasets to begin with. I had the idea to create a Community within Knoodl <http://www.knoodl.com/ui/home.html> that could serve as a sort of semantic dataset registry. The idea is that dataset owners can create instances of void:Dataset which represent their dataset and then describe them (using OWL) in sufficient detail that they could be discovered and then found on the web.
I started a Community in Knoodl called Dataset_Registry.<http://www.knoodl.com/ui/groups/Dataset_Registry> So far, all I have done is import the VoID ontology. I have not created any instances of Datasets, but I have set the permissions of the Community so that any registered user can edit any content, including creating their own instances. I am sure that I could take this idea quite a bit further if people begin to use the Community. If anyone is interested in this idea, please let me know.
