Other than those, NYT. It's usually not too bad but iirc they are dropping support for work arounds. It also seems to be posted with very high regularity and volume here.
I'd like a flag, but I don't want it to hide paywalled articles, but rather to just make them a different color. That way I can skip the link and just focus on the discussion.
I think this would cut down on most of the meta-discussion that happens every time a WSJ or FT link gets posted.
