+## Intended use
+
+- Patient/researcher exploratory analysis of self-reported chronic-illness experiences
+- Pattern-finding across thousands of accounts that single anecdotes hide
+- Generating hypotheses and leads to bring to clinicians or to peer-reviewed literature
+- Sanity-checking marketing claims and protocol recommendations against real reported outcomes
