— UPDATE 2020 : the theme is still working, you can go on and install it 🙂 —
Qone is a clean and minimalist WordPress theme for group blogging.
It looks as simple as a tumblr theme and is responsive.
It has special features like inline post edition and live updates.
You can download or fork it on github here: https://github.com/danielrico/qone
