Has Reddit’s traffic really quadrupled in 6 months? - lemm.ee

If they were just talking about Reddit, I’d assume something dodgy was going on connected with the IPO. But Quora is supposedly back from the dead too… Am I missing something glaringly obvious here?

Part of it is either Reddit manipulating search positioning or Google (most people's default search) prioritizing Reddit results. Searching for answers to questions often results in a half page of Reddit links. They may not be relevant, but that doesn't become apparent until you're there.
If you read the linked article it’s the latter. The explicitly say Google changed their algorithm and reddit consistently ranks at the top now. Even over the articles which the reddit thread is about.
