Just a reminder as you explore, reflect and annotate with hypothes.is: while you can technically annotate many password-protected and customizable pages, those annotations might not be accessible to others and they will likely be less than useful without the context to which they are attached.
For example, an intrepid Nousioneer attempted to use hypothes.is on Doug Belshaw’s book by commenting on the GumRoad (the book’s distributor) site. From her perspective, while logged in, the annotations might have context but for the rest of us—even if we login—the annotations are attached to an empty page!
That’s one of the reasons I didn’t assign hypothes.is when reading Doug’s book and something to keep in mind when you are choosing which tool(s) to use when engaging with an online (or kind of online) text. Kudos to Carolyn for jumping in and using hypothes.is though!
