Show HN: Trending media via Twitter API filtered by topic; Olympics example

I'm the developer, and this is a work-in-progress demo of a software package that processes and summarizes the statuses, photos, videos and links pulled from Twitter's streaming API. After supplying a list of hashtags, user accounts and keywords for a particular topic, thousands of tweets per minute (in this example) are mined and the most popular and rising content is curated for display. I am looking for feedback if people would find this useful for their own niche topics of interest, made available as a software-as-a-service package, open-sourced on github, or both. It's not perfectly polished yet...
