My main issue with it was that it places key elements such as the weblink you’re responding to outside the posting itself. It gets stored in the database as belonging to the PostKinds plugin. Meaning if you ever switch it off, that gets wiped from your posting (although it’s still in the database then). This was a dependency I needed to get rid of.
This crosses my mind from time to time. I depend on without fully understanding the Post Kinds plug-in. I am halfway between Post Kinds and IndieBlocks as I use Blocks a bit more. I’ve used them a lot on Glow Blogs and am less worried about switching to them full time. I wonder about,
deploying small templates that allow me to mark a posting as reply, rsvp, favourite, bookmark, or check-in, within the postings I’m writing.
as mentioned in Ton Zijlstra’s post.
I wonder if these are an alternative to IndieBlocks or something else. Can you make templates with the correct microformats in the Site Editor? But that would not work as semipress is not a block theme so I guess the template would be php?
