"we can adjust the threshold parameters as we see the need." Never mind the actual users being able to adjust them. This is what happens when you let things get so centralized, folks…

"as this evolves and we see our detection getting more and more accurate, we'll consider going to smaller hangouts too. but for now, we'll start with 4+ rooms." Hah.
