Relevant Meta Tags for Facebook Share

I spent the evening making sure the different pages on gave relevant titles and descriptions when shared on Facebook. The implementation was quite straight forward, but finding the finding the actual documentation for which elements Facebook supports ate a bit of development time. After navigating through four or five wiki pages at the development wiki describing various parts of the Facebook Share system, I finally found the page getting down to the metal about which elements you should include.

The page can be found at Facebook Share – Specifying Meta Tags.

We’ve currently implemented title, description and medium. We also had image_src, but decided against it at the moment – the first feedback we reserved made it clear people preferred to select their own image. This may however be because of the first batch of people being a bit too technical competent, so we’ll probably use image_src later (.. does Facebook support providing several images through image_src?).
