@aeryn This is indeed very confusing right now. Here's where things stand with notes:

• We currently only advertise this feature for Micro.blog Premium, but it's actually available for standard Micro.blog users as well. It is not available for Micro.one. So you can downgrade to Micro.blog ($5) and still have access.
• Sometime this year, we are going to split Strata off into its own optional subscription. At that time, no new users of Micro.blog will get it, but everyone with a current subscription before the change will be grandfathered in.
