Agreed about 1843, but it seems rare that they've got a proper longform article these days - or maybe they do but none of them are interesting to me.
Speaking of longform, I use Longform.org almost daily and just noticed that they're shutting down, or at least they're no longer aggregating articles. Wonder what happened.
I have been a subscriber for the past 20 years. Before I go further, I would argue my consumption model has changed even more than The Economist has changed. My consumption model has changed because the sources of deep and specialist coverage have increased. FWIW, I still find The Economist immerse-worthy, and I do enjoy it a lot. I have, however, increased my signal sources by subscribing to Financial Times, The Information, etc.
I like the long form articles produced 1843, a sister brand of The Economist.
All said and done, you and I probably are getting older, more cynical and The Economist is one in a long list of casualties :).
