I thought they were talking about Observables as in the Reactive Observables (1) from RxJS (2) et al.
Unfortunate naming! No doubt SEO will be super difficult for them considering how much "javascript" && "observable" keyword stuff there is out there already.
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.
That's for users who have never searched for anything regarding observables and clicked links which will tailor their ranking algorithm. Not sure how much optimization for "pure" ranking we should do nowadays.
I don't know the Observable folks personally, but I've been watching what they post on Twitter. It's not snobbery to say that the level of polish and sophistication present in what they put out (in terms of the reactive architecture and the graphic side of it) is second to none. Their product has got so much class that the idea that they would spend time on SEO is kind of incongruous, right?
