To make the chat room interesting both for visitors of Arduino.SE as well as other users within the Stack Exchange network, I think the chat room should be renamed.
The (new) name should be something related to Arduino which any enthusiast would understand. It could be something esoteric or something based on popular culture.
This would help in attracting users from the Network to the room, as every time a new post is made, the room goes on the active tab of Chat.SE, where it may get a fair bit of attention, if it looks interesting.
So, what should be the new name of the chat room? Also, what should be the room description that goes with it?
