I've been holding back on developing an authoring tool for STEM, mainly because I want to develop more experience in planning, writing and developing these interactions. The first couple I developed focus on using sticky notes on a whiteboard. This had some positives and negatives.
Event reports and write-ups are always a bit odd. They are only one person's viewpoint and filter, and only a selection of the sessions that took place. In these notes, if I've missed really exciting stuff - sorry.
