Bravo! When Twitter introduced annotations, I thought that was the beginning: soon, we would have Twitter classifieds, Twitter marketplace, Twitter as a data firehose for anything... All I was waiting for is annotations in the Search API. I'm positive that's all that was needed to provide the initial infrastructure for semantics -- the community would take care of the rest. Unfortunatelly, not only has it never happened, but Twitter took an entirely different course. I can understand them, though. They had to start making money fast and took a less risky road. But I can't help thinking: bugger, this could've been so much more than celebrities and hashtags.
