Done right, it can be an asset.
I'm on FR, which could be considered an echo chamber. From FR I get material which I cross-post to other sites which are NOT echo chambers. Similarly, Parlar can be treated as a place for conservatives to share memes and info, and copy to Twitter and elsewhere.
Content on FR is not private. You don’t have to be a member to read the content here. Jim was way to smart to do something foolish like that.
