Users who've been used to lurking on the social network will soon be left out of communities at the heart of the website, says Sarah Gilbert, researcher at Citizens and Technology Lab at Cornell University.

Reddit announced it will soon require users to log in to see much of the helpful human-generated content on its site. Why? Because traffic, and thus advertising, has taken a hit since AI started summarizing its data.
It's the latest development to threaten the old model of the open internet, says Sarah Gilbert, who researches online communities at the Citizens and Technology Lab at Cornell and is also active in r/askhistorians. She says the new login requirement puts up a wall between humans on the internet and is likely to discourage future contributions to the site.
