So if Section 230 gets repealed (ugh), my understanding is:

1. You can post anything you want on your own website and are personally liable for it.

2. If you host comments (syndicated or otherwise) you could be liable for what's said in those.

So the answer might be an #indieweb style interconnected blogosphere (yes, I said blogosphere) and more peer to peer style interfaces for #activitypub etc.
