To add a microblog to a new or existing WordPress site, simply install IndieBlocks, head over to Settings > IndieBlocks, and enable the “Notes” post type.
That’s it! There’s no dependency on other plugins.
It’s probably easiest to also have the plugin automatically generate titles and slugs for this new post type, at least for now.
Then, go and write a quick note, and hit “Publish”!
After publishing your first note, its web address should look a little like https://your.site/notes/random-note-slug/.
(Feel free to also add the new https://your.site/notes/ URL to your site’s main navigation menu!)
(Hiding) Note “Titles”
Depending on your theme, your note’s (autogenerated) “title” may be displayed quite prominently.
That’s where the “Hide Titles” option (again under IndieBlocks’ Post Types settings) comes into play.
Some themes, however, will require a more thorough template mod, or a bit of custom CSS, to properly hide note titles.
Taking It Further
You may want to tweak the “Archive” template, too. Add “Post Author” or “Post Date” blocks, if your theme doesn’t already show them. Or display notes in full, and not just excerpts.
Or create new “Single” and “Archive” templates for the “Note” post type, so that you can modify them separately from “regular” post templates.
