I also think you guys should re-think the categorization (I'm finding it incredibly distracting). If you remove the category name and give the link title more width (so that it's not truncated in many cases) - the title can speak for itself regarding the nature of the link.
Another +1 for removing categories. I find myself subconsciously ignoring headlines based on the category even though when I force myself to read it, it's actually something I'm interested in. Super dumb! But for me seems to be my human nature.
For what it's worth.
But love what I see and my social marketer has been forwarded the link and we'll keep checking it out.
