It's just a fun way to present some news about OpenBSD that the author cares about. What's confusing? There can be more than one website about OpenBSD.
as someone else reported, the confusing fact is that it's advertised as a webzine yet it does not come in the shape of a webzine.
it was more "magazine" layout previously, but they solicited feedback from the community that this single-page HTML layout was preferable to the "magazine" style layout.
