To the bolded, it *shouldn't* matter. Either way, a citizen has a reasonable expectation of privacy. It's a cop-out, but it obviously depends on the situation, too. Hulk Hogan is a public figure, but his sex-life isn't tied to his status as a public figure. Bill Clinton getting a blowie in the Oval Office, from a White House intern, is absolutely tied to his status as a public figure.
And the differences in those situations are exactly what I meant in my original post that you quoted. The legal definitions of "privacy" and how they relate to "media" and "public figure" are completely in flux right now because of the digital world we live in. Every situation is different when digital content is present, depending on who's involved, what the content is/was used for, and whether or not any laws were being broken.
Journalism is simply trying to keep up with USING technology as it advances... the field actually needs to be far more concerned with ethics, laws and regulations in regards to that very usage. As a relatively recent graduate of a journalism program, I can say that they are trying very hard to keep up... but one class and one adviser for the student paper aren't enough to teach potential journalists about ethics at the deep level that society requires.
The Hogan case (and his victory) was an important step in that direction. Not just because f*ck Gawker, but because reporting on something doesn't mean you also have to destroy someone's privacy totally and completely. You can report the fact that Hulk Hogan is a scumbag that banged his friend's wife... but posting his likeness, from a private residence and without his consent, is not necessary to report the newsworthy information. It's an unnecessary breach of privacy, and the ultimate judgement handed down is an important bench-mark that is being created for future cases, which is immensely important for both citizens and the journalists that will be doing the reporting.
