I've recently started using an asset manager for my latest app, and I believe they are becoming more common (rails 3.1.3 includes asset management).<p>Why would I use a package manager as a service when I can essentially do it for nothing?<p>Maybe I'm just not understanding your service. A few years ago, this might have been something I might be interested in (though I doubt I'd pay for it), I think you may have missed the market opportunity.
