An engine like telegra.ph?

Question

Blogs

There is such a site: telegra.ph
I would like the same, but only my own - to edit articles, of course, well, on my own domain so that.
The simplicity of the functionality attracts. That is, I went in and posted it right away, not in the admin panel ... It is
possible with authorization, but I would like something like that - so that you can also easily push the news. there.
Ease. Minimalism... what would you recommend?
PS Who knows the technical details on this site - for example, how many articles are stored on this site? There are no contacts, no rules...
Addition:
You can, of course, make a minimalistic theme on Wordpress. But it won't be exactly what you need.
