How are you using Reddit for marketing in 2026?

I've been running a Reddit marketing tool (RedditBlast) for the past 2 years and I've noticed most startups completely ignore Reddit as a channel. The platform has 1.5B+ monthly visitors but founders obsess over Twitter and LinkedIn instead. What's been your experience marketing on Reddit? Any strategies that worked or failed? I wrote a guide on how Reddit's algorithm works if anyone's curious: https://redditblast.com/en/blog/how-to-buy-reddit-upvotes/
