I've been working on some technical things the past month or so, and inevitably Reddit posts have shown up in my search results from time to time. One thing leads to another and I end up checking out the front pages (ex: popular and all) from time to time.
What I noticed now compared to when I "left" is that there are way more India-centric subs making it into the top results. Dehli, India Teens, Bollywood memes, and so on. So, I'm guessing that region is the next big push for growth.
