Reddit is going for an IPO soonish and they're trying to bump up their user numbers, so they're trying to get a different audience to their core 18-35 Anglosphere white male tech workers that were probably 90% of the userbase 10-15 years ago. To do that they're boosting subs for things like celebrity gossip, the royals, things focused on regions like India or the Philippines. Have a look at the top growing subreddits and there'll be a lot of those topics, and compare what the front page looked like a year or two ago to now, it's probably 25% now vs nothing at all back then.
