Basically, if all I can read is a headline how can I consider it informative? A news headline has as much evidence as your average Tweet, and can be deeply incorrect through the use of clickbait.
I do use methods to get around paywalls, but knowing that some/most people won’t, it seems counter-informative to solely use the clickbait headline to keep people informed.
Maybe the community should tag paywalled articles, such that those posts can be wholly filtered by users not wanting to see them?
