GoRails really filled the gap Railscasts left as Chris Oliver himself also states in this Interview.

He also mentions that for some people solutions to immediate problems are more relevant than constant learning via weekly screencasts. I hope he finds a way to offer these customers something, for example by selling course packages for a reasonable price, like all the recent „Vue.js with Rails“ screencasts as a package for XY$.

Overall GoRails is a great ressource for Rails developers, Chris Oliver seems to be a decent guy and I wish him best of luck with his projects.
