At last, an article that explains the state of the art. Now I have a framework of reference for how the Internet is built, what all those tools/coding/markup languages/etc mean and do, and how they fit in with each other. Things are making more sense.
It seems that my skillset is all in static webdesign (HTML/CSS), whereas dynamic webdesign was the doorway I couldn’t/didn’t get through. Probably as a result of that, I dropped out of the game right when dynamic websites were taking off.
And it looks like the days of writing markup/content in Notepad and then uploading those files to my host via FTP are well and truly dead. If I want to revive my old domain into a proper website I’ll have to find out what new tools are being used. And then, get some web hosting where I can tinker.
Next to investigate: What are static site generators, are they the “post-Web 2.0” version of WYSIWYG? How do I use them, how much effort do I need to spend to learn that, and is that effort worth it? Can I use a static site generator to blog? What, exactly, am I going to do with a domain (and not a microblog like this)? How will it enrich my life? How will it enrich others’ lives?
