The Feedster API has potential, but it's unclear what its purpose is. It would be more useful if it allowed content searches and provided metadata about searches, such as the number of blogs or pages a term appears in. Additional features like showing top searches and providing search result counts could be valuable. The current API requires a private key, which necessitates a proxy script for security. A simpler authentication method like Yahoo's Application ID would be preferred. Despite some limitations, the ability to publish search results as an RSS feed is a nice feature.
I'm developing an AJAX application to automatically generate Technorati, Feedster, and MSN search boxes with relevant tags for my blog posts. It's a JavaScript webservice queryer that uses results from one service as input for another. Currently, it only supports IE6/7 due to cross-domain data source import restrictions in Firefox. I'm exploring JavaScript code signing as a potential solution. The application integrates with Yahoo webservices, with plans to include Technorati and hopefully Feedster. There are security concerns regarding my Yahoo key. I aim to have a prototype available for feedback soon.
Thanks to Scott Rafer for the comment! I'm experimenting with providing topic search results rather than keyword searches to offer broader perspectives on a topic. RSS feeds are there because I like staying up-to-date, sort of like a personalized PubSub. I'm open to change though, so I'll experiment with adding color-coded boxes at the bottom of each post linking to Technorati tags, Feedster, and MSN Search results, all related to the post's topic to avoid tag spam.
