A new brand

Consider a new name (e.g. AJournal, NewJournal, TechJournal etc.), because it is difficult or also impossible to find it by searching for ABlog in search engines.

Thankfuly, you have added a URL to the tag generator of the Atom feed.

  <generator uri="https://ablog.readthedocs.io/" version="0.11.6">ABlog</generator>

I would further suggest to add the full name to the tag: "ABlog for Sphinx"

  <generator uri="https://ablog.readthedocs.io/" version="0.11.6">ABlog for Sphinx</generator>

Because this is what I see with a feed reader in HTML browser.
