(Note: This is a little bit of a plug for ideas I'm a big fan of, but it's not for anything I make money on.) I recommend you setup a project and encourage your users to use a feature voting site like the one we have for startups/hackers to use: http://featurelist.org http://featurelist.org http://featurelist.org/projects/add/ http://featurelist.org/projects/add/ There you can have your users upvote features and you can really see which the majority like best (rather than tracking all of them via email). Once I know what the users want, I rank the features internally using the method I mentioned here for getting a rough notion of ROI for each feature: http://news.ycombinator.com/item?id=122203 http://news.ycombinator.com/item?id=122203 The enthusiasm of your users on those features can help you calculate the business value (though other things should factor in). But you shouldn't decide to code them unless you've also calculated the cost (including some factor for long-term costs) of implementing them into your product.
