While writing this, I recalled that the Wikipedia
Android app displays
thumbnails in its search results. I think that's pulling from OpenSearch
with the PageImages extension[2]? but I haven't really delved into that
yet. I'm curious how those images get pulled - if it's taking into account
infoboxes or such, or just the first image on the page, or what.
It uses a scoring system that takes position on page, size and w:h ratio
into account.
Would it be feasible to include an og:image tag on
pages for which we have
a reasonable guess as to the thumbnail? Open Graph[3] is supported by what
seems anecdotally to me to be a wide range of services, so good hints there
would improve thumbnails for links on not just reddit, but Facebook,
Twitter, various chat clients, I think several Wordpress plugins, etc.
