Casting Your First Vote ​

  1. Browse categories on the home page or use the search bar.
  2. Select a subcategory (e.g., "Programming Languages" under "Technology").
  3. You will be presented with two items side by side. Click the one you believe ranks higher.
  4. Repeat. Each vote updates both items' Glicko-2 ratings in real time.

Understanding the Ranking System ​

RankHub uses the Glicko-2 rating algorithm. Every item starts with a rating of 1500.00 and a rating deviation (RD) of 350.00.

  • Rating -- The estimated skill or quality of an item. Higher is better.
  • Rating Deviation (RD) -- Measures uncertainty in the rating. New items have high RD (uncertain); items with many votes have low RD (confident).
  • Volatility -- Measures how much an item's rating is expected to fluctuate.

A win against a higher-rated item produces a larger rating increase than a win against a lower-rated item. See the Ranking Algorithm page for the full mathematical details.

Submitting Items ​

  1. Navigate to a subcategory's leaderboard page.
  2. Click Submit Item.
  3. Fill in the item name, description, and optional image URL.
  4. Submissions are reviewed before appearing on the leaderboard.

Viewing Leaderboards ​

Each subcategory has a leaderboard at /leaderboard/<slug>. Items are sorted by rating, and the RD is shown to indicate confidence. You can filter by minimum confidence level.
