 I've really loved with Hypothesis that we've been able to have kind of some of those preliminary conversations, really flesh things out and discuss things. And then I've been a part of groups before where we've just had Twitter chats and those can be great, but oftentimes you're only really getting at that first level and using Hypothesis, we're really able to get to that first level and then kind of take it to the next level in our Twitter chat. And then sometimes we'll even bring it back and folks will go back after the Twitter chat and make more annotations, put links in, do different things. And so we really get a lot of depth that I'm not sure that we would get otherwise.
