This is the first time I'm open sourcing my code. Please be nice. Any feedback is welcome.
And a twich for the occasion http://twich.me/opensource
I'd put it to technical incompetence more than anything else.
It's pretty cool seeing your site and what you decided to do differently. I'll be checking out your source later when I have time.
Mine is also built with php/node and I added socket.io so I could take advantage of websockets. I auto-log in users and keep chat history (although right now it only shows the latest 30 messages)
If you're looking to implement any features I have (like chat history) PM me and I'll share how I did it
I see twitch is using php to render views, but I was wondering if anyone has tried any js template engines? I've used jqote (based off of John Resig templating engine, I believe) and it's pretty nice, but I'm curious if anyone else has had experience with any other js templating engines.
Another good approach, if you're looking for something that specifically plays well with node, is to look at the modules page on the node.js wiki - it's served me well.
