Thanks for providing those links! I work on mortar and wrote the weatherme tutorial.
We just released a new version of mortar on Friday, with all new templates that should be easier to use. I'll be updating the tutorials soon.
The developer hub will be the place devs go to learn about building apps for Firefox OS. We know it's just HTML5, but we are also aware there are many other questions regarding app development, so we fully intend to fill those gaps. It's not quite as simple as "just" building an HTML5 site.
