Will and others, thanks for replying here. I thought it useful to provide some response here for posterity, for others who may want to use and better understand MicroID, ClaimID and this plugin.
I certainly do understand now -- and I didn't earlier -- that MicroID is properly implemented inside those div tags and that they serve purposes beyond ClaimID. So that certainly helps illuminate things here.
I personally would love a plugin that put the proper ClaimID verification coding into all of a site's pages, not just home and author pages, and not just other MicroID usage. Whether that's consistent with your intentions/purposes for your plugin, that's certainly for you to decide, and I wouldn't hold it against you if you chose not to build it in, I'd just keep looking elsewhere for broader ClaimID verification functionality.
In the meantime, I should mention that, even after upgrading to your new version 1.1, I'm still experiencing all the same issues and don't see the verifiability that you mentioned 1.1 should have:
Sites that use static Pages as the home page do have the same MicroID calculated as ClaimID, but not in the head/meta tags, so unverifiable by ClaimID though you say it should verify.
Sites that show latest posts on the home page have no MicroID at all for the page itself, only for each of the individual latest posts within. So can't compare ClaimID calculation, and also certainly unverifiable by ClaimID though you say it should verify.
I know now that the plugin isn't currently intended to provide ClaimID verification beyond home and author pages. Re: calculation, though, while I see a match between plugin and ClaimID for single posts, I continue to see mismatches between plugin and ClaimID for non-home static pages. As you requested, I'll contact you directly about that as an FYI.
Thanks for your help!
