I’m still a fan of the original guidelines for Linked data – paraphrased:

Give each thing a ‘permanent’ page on the web.
Put information about that thing on that page.
Put connections from that page to other pages to make it more easily understood.

Wikipedia does this excellently, without having to think about RDF/SW.

For me though, a SPARQL endpoint containing data is not the same as having the data on the web.

The metaphor that works for me is that SPARQL endpoints are to Linked data, as access to an undocumented SQL server are to CSV files.
