@J12t Hah. Great Q.
Depends on the audience. If they've already heard of Mastodon I start there and work up to Fediverse. I tend to stay away from decentralization to avoid the crypto feel unless I'm talking to someone very technical. I also often refer to all this as the open social web especially if I'm talking to people who witnessed the dawn of the web to begin with.
The open social web, hmm. We have a lot of moderation and #fediblock in the #fediverse already, however, and might get more if/when large internet co's with a different value system than what's prevalent in the fediverse today connect. Personally I don't believe that unqualified "open" is what we want.
I think we want "open for anybody who isn't out to screw us" or some (more polite) version of that ...
