I have one that I haven't seen yet in this, unless of course, I may be going blind? Well, anyways, my favorite, unexpectedly is just plain HTML. I would've never gone onto other langauges without first learning HTML. I started with it, then moved on to client-sides, then server-sides, then onto compiliation languages, and, well, HTML is just where I started... So, without learning it first, I would've never been in the world I live in now.
