Thanks for checking out MarketBrief. We just launched our financial news service, but we're constantly iterating on the quality and analysis of our articles, and our sights are set much higher than simply churning content.
I haven't had a chance to check out the site yet, but I can tell you from personal experience that putting these filings in a more usable form is definitely an area that is underexploited at the moment.
I often comb through filings for the super regional banks. The majority of my time is spent looking for a few key items and arranging the data into a useable format. If you are looking for more ideas on how this area could be improved, I'd be glad to fill out a survey or give you additional comments.
