Ask HN: We're looking for suggestions for API features

Our new startup, Repustate.com, is trying to shake things up in the social media monitoring and measuring field. A lot of companies are charging hundreds if not thousands of dollars a month for these services (sentiment analysis, keyword analysis, "brand reputation management" etc). We're trying to push the cost down to 0, but we need some help. If you go to http://www.repustate.com/suggest-a-feature/ you'll see we set up a little feedback section to hear from people about what kind of API calls they think would be useful. We'll build the best ones (for free) and then you can use them (for free) in whatever area of work you're in. For the MBAs out there, we call it our crowd-sourced API. So any help is highly appreciated and all suggestions are welcome. Thanks HN.
