If either some other up-and-coming, non-fediverse social media site implements rel="me" checking and presscheck.org gets used for that, or news sites allow rel="me" links from their writer profile pages -- ideally both, and also I think they'd both push each other forward -- then I think we count that as an unqualified #ReDecentralizeTheWeb success. (Possibly the first one?)
The rest of the stuff we're doing here I think is still experimental and fragile, I think, but the fact that as part of a composition of technologies all being self-supportingly together part of the fediverse experience we can get that succeeding is Good.
