Yes. And with the new front-end I expect growth to accelerate. In addition to channel fetching and auto-lookups, I want a "To be summarized" button, where users can simply go to a page and find a bunch of videos ready to be summarized.
Even further down the line I dream of an "Auto-summarize channel"-option, where you grant the summarizer posting authority for a limited time, and it will auto-post the summary-threads for you.
