This page is not part of blohard. It stands in for anyone's website, a blog, a newsletter archive, a documentation page, and shows what it looks like to give such a page a discussion section backed by the chain rather than by a comments company.
The page's author wrote one post on blohard for this page. Whatever people reply to that post is the discussion here, shown live from the chain and verified against it in your browser. The same conversation appears in the app and in every other client, and the page's author moderates it the way any author moderates replies to their posts: remove a reply, block someone, or set a rule for who may reply.
A comment section that the page owner controls and no company hosts. The replies are theirs to curate, and the record is nobody's to edit.
Replying happens in the app for now. The reply link under any reply opens the thread in a new tab, where your wallet already works.
