tldr; Generally speaking to "read", ie follow, posts on any ActivityPub (AP) site, a single acct on any AP site suffices. To "write", ie author, a video in peertube, or images in pixelfed, you need an acct in peertube & pixelfed respectively, as examples.

*mastodon sites, pixelfed sites, peertube sites, bookwyrm sites, funkwhale sites, etc, are all sites that use AP.
