Thank you for trying it out and the feedback.

1) I have increased the spacing between stories. Also, have you tried the Mobile view?

2) Looks like some websites are harder to parse than others. Some users have also reported similar issues with GitHub/Gists. Will investigate.

3) I've removed the rating for now. Will add filters to the roadmap.

4) I'm currently showing all 30 articles from the HN frontpage. Would you prefer fewer articles, but paginated?
