what are the newest sites that host that content not mainstream but on the rise

As of my last update in October 2023, there are several emerging platforms and sites that are becoming popular for niche content outside of mainstream venues. While trends can shift quickly, here are a few types of sites to consider:

**Substack**: Gaining traction for newsletters, many niche writers are utilizing Substack to share their content directly with subscribers without relying on mainstream media.

**Mastodon**: A decentralized social media platform that allows users to create their own servers, fostering communities around specific interests.

**Discord**: Originally a platform for gamers, it's increasingly being used by various communities for discussions, streaming, and sharing niche content.

**Patreon**: Not new, but it's still rising in popularity as more creators use it to fund niche projects or content that may not find support in traditional avenues.

**Ko-fi**: Similar to Patreon, this platform allows creators to accept donations and offer exclusive content to supporters.

**Raiders**: An emerging text-based social network focused on community building and curated content sharing.

**Letterboxd**: While not entirely new, this film-focused social media platform is growing quickly as a space for cinephiles to discuss and review films.

**Twitch**: Beyond gaming, Twitch is seeing growth in other categories such as "Just Chatting," where creators discuss various topics live.

Remember to check if these platforms align with your interests and stay updated, as the landscape of online content is always evolving!
