Maxim, I did notice your request to add the story, but when responding, it does not appear to be possible to leave feedback — there are just two buttons: “Accept terms and request” and “Not interested”. So I clicked neither. I’d prefer to keep these stories separate, as they are not solely related to Angular — although, observables are a major part of the framework. I have been compiling a list of Angular topics about which I could write (for example, there are some surprising behaviours with OnPush change detection and form validation) and I’d be happy to include those in your publication.
