Switch from CentOS 8 to Stream 8 instructions are buried under a few clicks on the download page

# Converting from CentOS Linux 8 to CentOS Stream 8                               
dnf --disablerepo '*' --enablerepo extras swap centos-linux-repos centos-stream-repos
dnf distro-sync

Upgrade transaction can work while not being completely up to date.

Do not enable vault, which is for archival only. Leaving it installed encourages the bad practice of using end of life software.

Apparently extras repo survives for 8 and there is where release packages for Stream (and SIGs) live.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
