I'm going to leave an annotation here, we'll see if anyone finds it :) So one of the things that was very powerful to me with Marlene Scardamalia's Knowledge Building (video) was how ideas could begin one place, and get reorganized as you developed your (community's) understanding.

One thing I'm wondering about is how to deal with that with Hypothes.is annotations - that's something we've been trying to experiment with in FROG (example), but I'd love more ideas.

In addition, and one thing Knowledge Forum also missed, is a forum for "meta-talk" - talk about the process of building knowledge together... Which is why I decided to leave this comment here - didn't know where else to discuss this?
