Over 8,000 subreddits have gone dark in protest of Reddit’s upcoming API changes, rendering Google a lot less useful without them. Reddit offers a vast library of knowledge on every topic imaginable, with smaller sub-communities creating mini-forums on niche topics. For anyone with specific questions or problems, Reddit is the go-to place for quick and detailed answers. Its conversational and highly communal feel creates a wealth of information, all in one place. The sheer number of now-private subreddits and the impact on the everyday Google experience demonstrate how much Reddit has carried the search engine for many people.
