Way over-long, but with plenty of meat on its bones:
So: why do I think bloggers should get away with that? Why is the left side of HuffPo fine and the right side questionable? Because people should be able to write about things. They should have the right to use them for: “purposes such as criticism, comment, news reporting, teaching.” The person blogging about news things at HuffPo is doing something unique, whether that person is insightful or an idiot. There’s societal value to both. It’s a tremendously important freedom and it’s why the blogosphere is so rich. On the other hand, just slapping up a quote above a comments section—which, odds are, the other site has as well—feels cheap (and, technically, is cheap, that’s the business model).
