I think the video does a fine job (music is a bit jarring, perhaps).

But I actually think the video is the least of your concerns. Right now, when I visit your site, I get no impression of what your site actually is -- a news aggregation site.

As it is, on the homepage all I see is "Tune your feed" and a lot of explanation copy. This all makes it look like an app or service.

Same thing on the video page -- after watching through the video, I had no firm grasp of what exactly you were offering because you never planted the simple fact at the outset that this is a news aggregation site.

Once I figured this out, it made a lot more sense. Advice: Before you do anything, make sure they realize what on earth your site is at its core -- a news aggregator. Then tell them why it's special.
