Geohashing IRC channel

At those moments that you want to talk about geohashing but everyone you know is either asleep or feigning death, turn to the #geohashing IRC channel. IRC is one of the oldest real-time internet communication modes, so it's simply a text-based chat room.

Connecting

Modern web browser it should Do The Right Thing when you click on the above link, opening a new window in the chat room. If that doesn't work for you, you may have to download an IRC client for your web browser, and if you're using a sufficiently duct-taped system that you need to do this, then you probably already know how.

Protocol

There isn't much. You can see who is in the chatroom (by the named green dots in the right-hand column, on Firefox). Sometimes people suffix their screen names with "afk" or "lunch" or the like if they aren't actually there, but not everyone does. Type in the text box and hit return to send a message. #geohashing custom doesn't include the whole chatroom chorusing "hi" and "bye" for people connecting and disconnecting and the only demographic information you'll be quizzed about is your graticule.
