The Fediverse isn't just sharing links to other platforms, it goes a lot deeper than that. Fediverse discussions and interactions happen across multiple platforms. This happens so seamlessly, you may not even realise it is happening.
For example, I replied to a PeerTube account's post from Mastodon, and my reply appeared on PeerTube (see screenshots).
The significance of the recent #Ghost announcement is people on Mastodon etc will be able to interact seamlessly with Ghost blogs.
