1. If possible, I would make the entire logo clickable. Not just the icon, but the text as well.
2. Title is incorrect when clicking out of a product.
3. Comments are a huge part of Product Hunt. I would like to see some more features implemented, such as possibly highlighting the original "AMA" comment from the maker and keeping it on the top. Also, sorting by highest rated comment would be great as well.
4. Search bar at the top might be a good idea, instead of having to click at the icon, then type my search.
