What is even the point of posting a paywalled article to a forum like this? Anyone who puts content behind a login does not wish it to be linked in an open forum. Period. If the WSJ wants their articles shared and discussed, they should build and maintain their own HN behind that paywall and keep it there.

Your suggestion of going via FB makes things even worse. Now there are two walls involved in keeping others out.

Or am supposed to keep a plethora of logins at hand just to participate in an open community?
