+question: Why does the visualized data look so boring?
+---
+Those who participated with this tool early on may have seen that the data
+seems to be more interesting back then. There were 3-4 opinions groups all
+favouring a high degree of electoral reform, and each group had a story to
+explore in the data.
+
+Sadly, a current limitation of the tool caused this to change. When new
+participants supporting the current first-past-the-post system started
+arriving, they caused the other groups to "collapse" into one. This was through
+no fault of the new participants, but was simply an artefact of the current
+mathematical modelling. The "stories" (along with others) are still buried in
+the data, and can be teased out once we [release our open dataset](#open-data).
+The issue is that the tool and visualization simply aren't robust enough at
+this point, and unfortunately won't be remedied over the duration of this
+particular consultation.
+
+The Polis team are definitely thinking on long-term solutions for making the
+data more explorable by all participants, and also more [short-term
+solutions](https://github.com/pol-is/issues/issues/39) for moderators.
