A blog theme's job isn't just to render posts one at a time — it's to help someone find the one they actually want. Sirocco gives a visitor three independent ways to do that, and this post is deliberately tagged with four different terms so you can try all three against it.
Tags
Every tag on a post — see the row at the bottom of this one — links to
/tags/{name}/, a real content page the demo generates with
termPageFor and a @taxonomy.tag collection. Tag a post, re-link the
demo (or author the matching term page on a real site), and it's
discoverable.
Search
The header's search page queries /api/search directly — try searching
"organization" or "tags" from here and this post should turn up.
Archives
The Archives page groups every post by year and month, newest first. It's the one view that shows you everything at once instead of the home page's one-page-at-a-time listing.
Three different entry points, same underlying content — pick whichever fits how you're looking for something.
