Ok, so @David_Tschumperle poked me earlier to possibly set up an IRC channel dedicated to the site for real-time discussions and whatnot. So I did.
We are on irc.freenode.net, channel: #pixls.us.
If you don’t have a client and want to connect through a browser:
http://webchat.freenode.net/?randomnick=1&channels=%23pixls.us&prompt=1
Feel free to pick a better username than the random one that gets assigned… 
I’ll be adding this info to a re-worked About page for the site soon.
