Urls with /content/

Hi guys!
Seems we have 2 different approaches in the Drupal website about linking urls.
Some Basic pages have an URL Alias as "content/foobar" while others have an URL Alias as "foobar".
Which is the standard way that we should follow?
It's not beauty(and a nightmare) having both conventions.
From my pov, I think reactos.org/newsletter is better than reactos.org/content/newsletter.

Btw, remember that when linking to them you dont have to use reactos.org/newsletter.html (look at .html) or the link wont work,
