You can follow anyone from any other Mastodon server here, which will enrich our "Federated timeline". This one look pretty good: https://mstdn.foxfam.club/public
Just put the full handle of the account you'd like to follow (i.e., @handle@mastodonserver.wherever) in the search box above, & then click follow when they're found.
