i think it's more about a certain mental shift than watching a screencast. a similar "mental shift" to getting comfortable with unix, regular expressions (not just perl), and such. that sort of unix'ish freedom is how i get things done. i don't think you get that with a screencast spoonfeeding what characters to type, and it would most likely miss the point. yes it takes time to stay interested and keep up with new (and old) technologies, by reading lots of internet and book resources. i like to learn about all different technologies, and sometimes it all comes together in a project. i try not to bias towards perl or javascript or anything else. once an idea of something comes to mind, i try to imagine how things work, regardless of implementation. then once the interactions/functions are clear, the parts come together using particular technologies for the client/server etc. anyway, getting to philosophical
each of us take their own path. i personally don't think it's necessary to have a whole heap of screencasts for perl. Those interested/hooked will learn in any way they can. There's enough free help out there for perl, including this great resource, to help those that want it.
