Comment on: Show HN: TikTok but for Scientific Papers

What I don't understand about these specialized social networks, that obviously won't exist in a few months as they won't get traction, is why not just use the existing social networks?Instead of some LinkedIn / TikTok / Facebook / Insta for X, create a group or channel in an existing network. Create a subreddit, or Facebook group or telegram channel. There are a number of existing social networks that are good at creating sub-communities. I don't want to join another social media platform.
