That’s really nice, yes! It makes it look very simple.
Regarding titles, I get what you mean. You know, Facebook has started introducing them in groups. Want to know what they look like in my community? 
Of course we can educate people, and we will. But this is what’s probably going to happen if I let my “base” community members loose on Discourse.
Here’s an example of a less “Title in your face” interface:
The title clearly presents itself as optional. The focus goes in the post body, and not on the title. Even as an OG blogger, seriously, I find nothing more paralysing than having an idea for a blog post and being faced with a blinking cursor in the Title field. Thankfully I’m all grown up now and I move my cursor to the post body and start writing, and come back later for the title. But it takes insight and willpower to disobey the implicit order of a form on your screen 
So here, I’m invited to start writing. I can, if I want, set a title.
How could we manage this in Discourse? Well, if no title is set, use the first few words of the topic. More senior members will fix the title if needed later. But in the meantime, it won’t have created a bump on the road to posting for the first or second time for a new user, and the value contained in the automatic title probably won’t be lower than “coucou tout le monde” that we’re likely to get pretty often.
I know this title thing is a sticking point for me and not everybody sees things that way, so maybe it’s a case for a plugin/component (which?) of its own.
