Thank you! Inspired that I inspired you because I used to read this type of thing and thought I'd never do anything like it.
I've thought about expanding to additional freelancing sites but have not thought about the RSS+notifications thing. I still have something eating away at me that it's just an "RSS feed reader" but maybe I'm wrong about that entirely.
Just do this but for other job sites and aggregate. You seem to know Pieter Levels from your Make book reference, and I'm not sure if Remote Ok has an RSS feed or Slack notifications but this could be a pretty useful feature for that.
Also add categories and keywords to filter by for Upwork jobs if you haven't already. Contact Upwork users directly and message them about your product. Do things that don't scale as they say. I'd say contact maybe 500 people and see the response and subsequent sales. You could also contact marketers so they can post their jobs on your platform perhaps. There are many ways for future development it seems to me.
You can email me if you want more advice, I run a SaaS as well (https://getartemis.app) and I do some of these marketing tips I talk about.
