Just a quick update.
I've written up an about page with some background and history about Instaud.io, providing a bit more context for new or curious visitors.
EDIT: Since I personally don't use IRC anymore, the below info no longer applies.
Additionally, I've started an IRC channel over on Quakenet, where you lovely people can come chat. You can either use Quakenet's webchat to get in there, or, if you have an IRC client, use this irc link: irc://irc.quakenet.org/instaudio.
It probably goes without saying, but try and be nice in there. There aren't any specific rules, but if you behave in a detrimental way on there, you'll likely be kicked out or banned (with warning, of course.)
