Piazza Likes is a Chrome add-on developed by barric.reed that allows users to collaboratively like comment threads on the popular class forum Piazza. With Piazza Likes, users can easily sort comments by post time or number of likes, enabling them to quickly find the most useful comments in active posts.

One of the key features of Piazza Likes is its similarity to Reddit's upvoting system. Users can like comments, and these likes are aggregated across users. This aggregation feature ensures that the most valuable and helpful comments rise to the top, providing users with a streamlined and efficient way to navigate through discussions.

To use Piazza Likes, users simply need to install the plugin, log in with Firebase Authentication, and start liking comments. The user IDs are used to track likes by comment IDs, and the likes themselves are stored in Firebase Realtime Database. Additionally, the Piazza DOM is enhanced with a sort panel and like options, making it easy for users to interact with the add-on.

The latest version of Piazza Likes, v2.0.3, brings a fix for the sort menu that used to hang around when swapping to non-comment pages. The previous version, v2.0.2, improved the sorting by likes feature. And in the major overhaul of v2.0.0, upvoting and downvoting were changed to likes, and the sorting panel was re-done.

Enhance your Piazza experience with Piazza Likes and make the most out of your class forum discussions!
