OurSignal.com looks at currently popular items on the social news sites of your choosing and mashes them all together. The idea is to allow users (you especially) to get a rapid overview of the latest breaking headlines that match specific interests.
Create your very own customized oursignal and share it with others
Add/remove news sources e.g. Mashable, ReadWriteWeb, TechCrunch
Use sliders to assign relative importance to each news source
Pick from a range of 'visualizations' to suit your reading style (bigger links are more important, hotter colors are items on the rise)
If multiple sources mention the same url (e.g. http://trendsmap.com) then those items are combined and considered more important
Access to RSS/XML/JSON output for developer mashups
