Why I chose Medium.com
medium.com
medium.com
I feel that Medium doesn't give the user any difference between "jack" and "joe". Sure, their content may be differnet, but from a design perspective it's basically all the same.
Some people may like the similarities, but for me it goes against what the internet is used for: Being unique and differnet in your own personal way.
You may disagree, that's fine. Just my two cents.
