In all honesty, porn. While reddit somewhat backtracked on the third party apps debacle, they silently made nsfw reddits only available on the official app, which makes everything a fair bit more difficult. As someone invested in foss communities, Im not about to download some spyware app just to see tits on the internet, but doing that from a web browser is combersome and somewhat dangerous due to javascript. As a result I come here, but recently ive just been using it to engage in discourse before deleting all of my comments.
