A Microsyntax for Getting Thumbnails Given a URL
I don’t know if this classifies as a microformat/microsyntax, but this would be cool: standardized URL structure for photo thumbnails.
Eg, the thumbnail for
http://twitpic.com/7qb91
is
http://twitpic.com/show/thumb/7qb91
You could imagine thumbs being useful for videos, product pages, album artwork for links to songs, etc. Standardizing syntax for thumbnail URLs given any URL would make it very easy to enhance any simple text stream with preview images easily.
