I finally got a Windows Live Writer plugin working after starting from scratch! Stay tuned as I'm planning to integrate my Ajax Tagger into the Windows Live Writer framework soon. This will be a cool experiment combining Web 2.0 APIs with Windows Live Writer.
My tag directory has a cool new feature: Amazon product integration! It pulls book data from Amazon AWS related to each tag. Right now, it adds links to relevant products, but I'm thinking of adding images soon. This latest addition brings the total number of Web 2.0 APIs used in my mashup to four, including Delicious, Yahoo Search API, and Google Blog Search RSS. Check out the examples for tags like RDF, RSS, and Mashup to see it in action.
