Once upon a time Reddit was a link aggregator. You would post a link and the author would get credit. You could save the link without Reddit. But Reddit is moving towards first party content. Not only has the site added native photo and video upload support but many communities disallow external content. Requiring a reupload or a screenshot. This not only removes the link to the actual creator but is also a nightmare…
Now, no more. "Check out this link" is not an enticing offer, it's assigning homework. I don't know if it's because neat stuff is no longer rare and we've collectively had our fill, or because everything got so co-opted and corrupted that we go in to every new site with one wary eye watching for the dark patterns. But one way or the other, people don't share links. They share memes instead, which ask far less of us, and are much harder to monetize.
