Tom Heath recently wrote about RDF Browsers in the IEEE Internet Computing Journal.

It's at the level of "things" that browsers for the Web of data should operate. Providing simple browsers for RDF triples, and the documents in which they’re published, is one option for enabling people to interact with this information space. We saw this trend with some of the earliest Semantic Web browsers, but it rather misses the point. The one-page-at-a-time style of browsing, which we know well from the Web of documents, would make nothing of the potential we now have for integrated views of data assembled from numerous locations.
