Self-selected online poll, no accounts: one vote per browser per day, capped per network address to limit repeat voting. Country derived at the network edge; age and profession self-reported from fixed lists. Buckets under 25 votes fold into "Everywhere else"; buckets under 5 are never published. Not weighted, not representative of any population.
