 I think we're seeing both from Addy and Emily here at like the power of social annotation to kind of change how we think about publishing. For so long, we kind of give students these curated texts, and they might note on them right they might write on them in the margins but they're not able to make that public. And so the public component, the collaborative component, it's just really cool to see students be able to kind of highlight what they value, call into question texts, and then of course make these really cool connections that we haven't seen before. And so something that we try to do at Rebus is really encourage everyone to be a part of the publishing process so that it's not this like one way street, your student come in the class get the information and leave. It's more collaborative in both ways. And I think social annotation is just one really cool tool on our in our toolkit to do those kinds of things.
