Your comment made me curious about our current SEO rankings, so I used a VPN and fresh incognito windows in a browser I never use (Safari) to Google for "observable" from Silicon Valley, New York City and Madrid.
ObservableHQ.com is in the top spot in Silicon Valley and NYC, and a few spots down the first page in Madrid, after Angular Observables and RXJS Observables. So it looks like we’re doing pretty alright so far.
