> XHTML was a ladder rung into the semantic web. A distributed knowledge graph that could be mined, remixed, and extended with little effort. The first attempt at that "knowledge graph" thing was the "keywords" meta tag. Its failure should be taken as instructive regarding the difficulty level of the project as a whole. > It was marginally harder to author (the mimetype issue was ridiculous), but extending it was low hanging fruit. Silly me, I thought it was more about mandatory strictness vs user-generated content, rather than what mime-type the server had to label it as.
