Looks good to me! I went straight to the site without reading your post and was confused about what I was supposed to be doing, but I did come up with some some silly headlines.
Yeah, it's in early stages, so I've not gone as far as writing hints/instructions into it to set expectations. It's based on the TodoMVC apps, so you can double-click an existing headline to edit it, but I'm still working out how to best enable that functionality on mobile.
