Yes, that is what I mean. But I think this is less a text/copy problem than a design/layout problem. You should probably make the articles the front page, like Hacker News/Reddit/Digg. There's a reason that's the standard. Burying the articles section of a social news site just doesn't work.

You will have to be clever about how to make it clear that there is something different about how your news site works. A big "How It Works" link at the top, or embedding your explanation video in the corner next to articles might work.

The main feature of Hacker News/Reddit/Digg is that such site provides "front-page articles" which was upvoted by the community, so put it on the homepage makes sense.

Tagmask idea is to provide personalized feed for each user. So, that's why its structure much like Twitter/Quora, they also didn't display any posts on the homepage.

You were right! I am working on the live demo of Tagmask (it's based on posts list http://tagmask.com/posts) and will put it on the front page. Thank you very much!
