That does seem to match what’s in the FAQ, where it says Bubbles is for “People who enjoy reading blog posts about things other than startups and JavaScript frameworks.”
Since that’s… most blogposts, this strikes me as a project that could stand to narrow its scope. I’m reminded of the times when I’ve prompted my students to identify a target audience and they simply responded “the general public.”
I share the same sentiment. If someone’s telling me they can identify “today’s best blog post” on my behalf, I want them to tell me their criteria. If their criteria involve Reddit-style popularity contests then I expect we have different priorities.
