For most types of notes, the default “Context” block is probably okay. Certain types, however, like “reposts,” could benefit from additional microformats.
We’re experimenting with additional blocks and block patterns—simple blocks can only do so much—for “slightly more” experienced users.
Alternatively, each Context block can be converted to a Custom HTML block, making it possible to go in and manually edit its structure and microformats.
(You could also leave the block as is, and choose “Edit as HTML” instead, but most changes would be undone as you switch back to the visual editor.)
Either way, IndieBlocks’ goal isn’t to become the be-all and end-all of “IndieWeb” solutions for WordPress. Rather, it aims to make it easier to get started.
