ATproto might not be a platform exactly, but it is an ecosystem. Programming language ecosystems don't really die but they do fade sometimes.

I think the issue with publishing via a PDS is that you're basically letting anyone republish on their own website. For comments that makes a lot of sense since they can show up under articles. But for a blog? Maybe it would be better to keep your database of articles offline, publish it to your own website, and not replicate it to the world? Instead, send a ATproto post for each article with a link to your website.
