Contacting Hamlet Learning Communities

I wasn't quite sure what would be the best way to approach this.  I was hesitant to send out mass messages contacting other learning communities for fear of being construed as a spammer, so I split the work with Justin Thompson (admittedly, it also made the work easier).  Once I had decided on this, I figured Twitter would be a decent place to start.  I searched for the people tweeting things about Hamlet.  Not being exactly sure what I was asking for, I started with a general statement asking for their experiences with Hamlet.  Twitter presented the unique challenge of 140 characters, which may have hindered the effectiveness of communication.  Neither of the people I contacted have replied, but I will update this post if there is a change.  However, I have my doubts that two random people on twitter will care enough to reply,especially if it means extending the conversation.
