This was the first time we actually used MeetingSphere and I’d say that it worked well to collect a lot of questions (see this topic for a complete list). However, I was surprised to see a lot of very specific questions that were, IMHO, not directly about the state of meeting research but rather questions that would be studied in the field. Either I did not adequately express the task at hand or people were worried that if their specific research interests are not reflected in the list of questions, they will somehow loose out. Or both. Or people simply wanted different kinds of guiding questions that what I had in mind.
In any case, the list became very long and I felt unsure how we would manage to go through all questions let alone merge and refine similar ones. So I spontaneously decided to sort the questions into broader categories (folders). We managed to do that in time and since the resulting these 12 clusters of questions:
Since this list was already close enough to the envisioned 10 guiding questions, there was no need (or so I thought) to do the sticky point exercise. We already had our 10 12 guiding questions. 
Or had we? - Unfortunately, we did not have time to look at each of those clusters in turn and formulate actual questions that we would then explore in each of the following sessions. Of course we don’t know how useful those questions would have been in the thematic and open sessions, but in retrospect, it seems pretty clear to me that this part of the opening session did not work as I had anticipated in terms of producing questions that would guide our discussions during the symposium.
What we did produce is an incredibly interesting list reflecting the diverse research interests in the field of meeting science (or meeting research, as many seem to prefer). Let us use this resource to explore these questions here in the forum! And by “us”, I also mean those of you who were not able to attend the symposium.
