What commenters say

• Some commenters found the experiment to be a cool and innovative demonstration of multiple window interaction.
• Others pointed out that similar experiments have been done in the past, and the concept is not new.
• The use of window.screenX and window.screenY APIs raises concerns about privacy and fingerprinting.
• Some argue that these APIs are not a significant risk, while others believe they could be used for malicious purposes such as clickjacking.
• The discussion also touches on the potential applications of this technology in fields like augmented reality and gaming.
• Some commenters suggested alternative approaches, such as using LocalStorage or BroadcastChannel, instead of sockets.
• The experiment's potential for multitasking and reskinning environments is seen as a potential benefit by some, but others are skeptical about its practical uses.
