Some NeoGAF users have discovered new details on the Nintendo Switch’s Online Lounge App by fiddling around with the Nintendo Switch console, including its name. Indeed, the app is 100% needed for lobbies and chat.

Most of the discoveries, however, involved some hints on how it will work. Buried in the console is, to some degree, the lobby function. The function is done via a web applet that is makes requests towards a page that is hosted the official domain Nintendo uses for their network. The following message was also discovered in the source code of that page:
