In this inquiry, I am assuming you are blogger / writer. What content would you expect to find on a specialized website training site? To tie in with that question, what website development languages would you expect to learn for your blog?
I would have never expected anything like development languages… a blogger is a writer, and doesn’t develop sites, just use them. I would have expected articles about typography, writing style, copywriting, differences between copywriting and regular article writing, goal achievement… and so on
For a blogger to begin website development there are the two basic languages, HTML and CSS. That is the two languages I would hope a blogger would learn first if he/she was to create her own website. I hope this answers your question, I am unsure of what you were actually asking but hope this helps.
