Definitely some good advice. Although I probably won't make it like a blog, I do agree that each item should be linkable. That's something I wish I'd done before submitting it. Hindsight! But those are all features I think I should incorporate as soon as possible.
So, add:
- Tags
- Categories
- Filtering (most popular, saved, etc)
- Saving
- Blog style (so people can direct link, or just provide direct link)
- Similar items (via categories or tags)
