I think we need a serious discussion about paywall content.
Personally, I am very annoyed by paywall content and I would prefer to don't see it on HN.
I think that paywall content are a serious treat to the openness of the community.
The recent trend in paywalling is a negative one but it's not easy for any one aggregator (who isn't google) to punish the behavior. Consequently, a lot of a great content is paywalled.
Is there a recent trend? The situation has seemed stable to me for a long time.
The last big shift was the New Yorker switching to a ponywall (i.e. letting incognito windows work) which, whatever it did for their economics, made the web and HN way better. Nautil.us recently introduced a paywall, but they love HN and are letting HN traffic through.
