Semantic Web and Privacy

There was an article about the semantic web and why this may be a problem with privacy. According to one academic:

Privacy problems could occur, he said, because the semantic web deliberately combines multiple sources of information about people and places.

However, even if semantic web should create a problem for privacy, I think it would be naive to think that privacy even exists on the internet. For example, if someone had created a web page and included their personal information, then he/she had waived some of their rights to their privacy by making some of their personal details available to the public. Probably, a more pertinent example is companies/individuals collecting information about other users online. A recommended book to read is Solove's book on The Digital Person!
