LibraryThing recommendations!

LibraryThing Recommendations—called "the best feature on the site" by one user—are back and much better than before.

You can find recommendations at the top of your profile page. Or check out mine.

The new recommendations include:

• A large number of primary recommendations for ever member—usually 1,000—based on a single comprehensive algorithm.
  
• Individual recommendation lists for each member's tags.
• Filtering of recommendations by popular LibraryThing tags.
• Individual lists of other members' recommendations (member recommendations were added two weeks ago)
• Up to 500 so-bad-they're-good recommendations, building off the LibraryThing Unsuggester, and called "Your Unsuggester."* We hope "What I shouldn't read" has some meme legs.
  
• A "why" feature for each recommendation, laying out what the recommendation was based on.
• A pony.**

I let the recommendations themselves out early—see the original talk post, with over 140 messages!—and members had mostly positive reactions. Those who don't like them can perhaps be molified by the greater number and ways to filter and angle the recommendations.

Recommendations now change daily—faster if you are below 200 books and keep adding them. The system keeps track of all recommendations and when you received them. In the near future I plan to provide personalized recommendation emails based on new recommendations.

I've created a new Talk thread to discuss the changes, and suggest changes. My thanks to those who participated in the initial thread, influencing development in a number of important ways.
