Lots of the alternatives seem to be missing the core idea of what Reddit really is (a community of communities). I think first and foremost it's the community aspect of Reddit that makes it appealing. I've been building a platform called Sociables which is intentionally not just a Reddit clone. We are trying to create an all-in-one place for people to create communities and not just posts. Here's an example of a comm…
But how does it work? Who moderates the communities?
Here's a list of the core community features:
1. Customizable discussion boards. Community owners can setup threaded discussion boards for different topics related to their niche. Say a user creates a community for a niche like "Cars", under that community they could create different discussion boards for sub categories like "Car-mods", "Car-photos", "Car-sales", etc. This is different from Reddit where typically you only have a singular discussion board per community.
2. Voice chatrooms. Community owners can setup Discord style voice chat rooms where users can communicate via voice.
3. Real-time text chatrooms. Currently we only have a singular chatroom for the whole community however we are looking at adding the ability to create multiple rooms per community.
3. Synchronized YouTube/Vimeo player. Community owners can create a playlist of YouTube/Vimeo videos. Their community's player cycles through the playlist and synchronizes the playback so people within the community can watch the same video at the same time.
4. Baked in monetization. Community owners can offer tiered monthly membership subscriptions that allows the members to support the admins and mods. Owners can also link their PayPal to receive donations. Also adding paid post bumps and comment awards that users can purchase where the revenue is shared with the community owner.
