Platforms that allow users to submit, share, and discuss content come in various formats, ranging from link-aggregators to social news and community forums. Here are some of the most popular platforms:

• Reddit : A massive network of communities (subreddits) where users can submit links, text posts, images, and videos, then upvote or downvote content and participate in nested comment threads. Check it out on Reddit.

If you mean platforms where users can submit their own content and then have other users discuss, comment on, or vote on it, there are several types:

Reddit and Hacker News are particularly close to the “submit → community sees it → discussion/voting” model. Stack Exchange is more structured around questions and answers, while Medium and Substack emphasize publishing rather than community voting.parse.gl+1

If you're asking because you're looking to build a platform with this model, the generic terms to look for are user-generated content (UGC) platform, social news platform, community platform, or discussion/forum platform.parse.gl
