My interview with @blaine, who was there at the very beginning of Twitter; now he's focused on building #fediverse infrastructure that will help #Mastodon scale. https://thenewstack.io/why-a-twitter-founding-engineer-is-now-all-in-on-mastodon/
I saw a post somewhere yesterday that public posts become searchable via Google.
On Google, you can enter:
site: instance keyword
to search an instance's public feed for a keyword. e.g.
site: sciencemastodon.com indexing
Far from perfect, and will always lag content by a while (until Google's crawlers find it), but potentially of use.
