HN NFR: Hacker News New Feature Request

I enjoy HN a lot, but I would like to see it improved a bit better. Nothing major, just a few more basic features will do.

1. Statistics Page. Counters of total registered users, total posts per category (like Ask HN for exp.), total comments per category, Total upvotes and downvotes for articles and comments.

2. Top Users. Similar like ledger, but with a bit more details like total posts/comments this users made, and there upvotes/downvotes.

3. User Profiles. A better way to add specific information like website, email, location, name etc. At least for those who choose to share that on HN.

4. Filters & Sorting. This maybe the biggest one for me personally. A better way to search on HN with filters and sorting. Like for example; keyword filter:security sort:byDate

5. Keywords or Hashtags. This will be useful for things like Filters and Sorting. Just a third textbox under title/url for this will do. Example; word1, word2, word3

(Any other ideas share in comments.)

And to all HN team thank you for keeping us entertained all this years!
