Things to look for:

• A per-page “share to FB”. https://developers.facebook.com/docs/sharing/web
• FB markup: https://developers.facebook.com/docs/sharing/webmasters#markup
• A per-page “share to G+”
• G+ markup?
• Twitter meta-data: https://developer.twitter.com/en/docs/tweets/optimize-with-cards/overview/summary
• Microformats v2: http://microformats.org/wiki/microformats-2
• RSS feed for “blog” page?

From http://www.kevinmarks.com/partialsilos.html: G+ will parse the FB “open graph”.

It links to http://schema.org/Article which is Meh2.

I’m not sure I want “share buttons”. What I’d like however is being able to tag a snippet + target image with an izu-tag and then let it generate the sickening tags automatically.
