Michael Kinsley has a very smart article on the wordiness of newspaper conventions in writing. Felix Salmon gets rather wordy on the differences in production that he says result in some of those newspaper conventions, but he doesn't make the connections clear.
I'll distill it down to a single difference that neither mentions: hyperlinks. Much of what Kinsley objects to, the wordy identifications of people we don't know and probably don't care about, can probably be omitted. But if there's any reason at all to include a person's name, the identification (and perhaps life oeuvre) can easily be supplied on the Web with a hyperlink.
By and large, the big newspapers haven't figured that out. Or the other fun and informative things that any good blogger has figured out can be done with hyperlinks. Instead, in their Web editions, they link random words in a story, frequently not even the most important ones, to their search machines, which frequently give boneheaded results.
