How to talk about the HoloNet, websites, social-media services, and other electronic forms of communication
One fan suggestion is to use gayi'kaab might refer to any device that transmits audio and information, based on how the English word "radio" has experienced a broadening of definition. Thus, gayi'kaab could be used to refer to the HoloNet within the Star Wars universe, and could refer to any single social-media service (such as Discord, Instagram, etc.), a website, broadcast television, broadcast radio, and the like on Earth.
The fan word kaa'yust is specifically "channel" (sound-path), but it's gained broader meaning over the years. Kaa'yust could be used to refer to a specific server (or specific channel in a server), a forum or web page on a website, a channel for TV or radio, and so on.
