How much would you give it out of 10? I am not impressed with the user interface or home page of many startups. As a test of how the hacker community thinks, let's rate the hacker news UI. Mine: 9 out of 10.
8/10. Nitpicks:<p>No top button when viewing a comment - only parent. No way to undo/reverse a vote. Comment reply/edit is on another page instead of inline like reddit. No comment reply notification in the toolbar.
I give it a 6/10 I guess. While I like the simple approach ... I am also missing a few basic bells and whistles. I'd love to see a search feature and/or a way to tag or categorize posts for later reference. Sometimes I think "oh, I remember reading about that on YC" but its nearly impossible to find again.<p>Also the text (as I'm typing this) in the form field is too lightly colored and the text area is too small for me.
Overall 8/10. It does everything it needs to in a really clean way. It's reliable and consistent.<p>My biggest nitpick is reading the grayed out font on visited links, submission text, and a few other places. My brain wants to skip over grayed out text so much that it requires an almost conscious effort.
