Don't Bloomberg and Reuters offer something similar built into their news feeds? Not that this would negate what you are doing, just wondering.

As far as we know, they also aggregate news on commodities, but we analyse and aggregate the news by commodity and by identifying price movement information. We also provide a large number of sources, bringing in news from many different providers, let them be new sites, blogs, research papers, etc.

We do (Bloomberg), but on equities, not commodities. We are working on it though :)
