Hey Josh, Zach here (one of the co-founders). We personally don't use PHP very much but we're more than open to hosting those screencasts. If you have any recommendations or would like to post some yourself please let us know.

I am still learning my self hence why I would love to see some screencasts. I am about to start a year long placement where PHP is the language of choice so maybe in 6 months I may do something for your site. Great work so far.

Also adding Go(http://golang.org) would be great.

We're definitely planning on adding Go. Do you have any screencasts that you enjoy in particular that'd you'd like us to add?
