Poke Holes in My Startup Idea

Would be awesome to get some feedback on my idea.

Here goes: Simply, to create a news site (and eventually mobile app) that aggregates the best content on the web for a given news topic ie "Egyptian Revolution" or "Japan Earthquake" on a single, digestible page.

The key will be for the company itself to curate the best content (link to the best blog posts, editorials, infographics, videos, etc), provide good context for the news story (a timeline, wikipedia background info), and be highly visual/design focused for a more engaging news consumption experience (maps, videos, images, graphics, etc). There will also be a "discussion" element, showing tweets and potentially a Facebook powered comment section.

Let me know what you think. Thanks all..
