Comment 6 for bug 620537

I've written the necessary code for all the projects. The code branches are:

  lp:~andrea.corbellini/launchpad/ubuntu-font-620537
  lp:~andrea.corbellini/launchpad-news-wordpress-theme/ubuntu-font
  lp:~andrea.corbellini/launchpad-help-moin-theme/ubuntu-font
  lp:~andrea.corbellini/+junk/lp-dev-wiki-theme-ubuntu-font

I've replaced all the sans-serif fonts with:

  UbuntuBeta, Ubuntu, 'Bitstream Vera Sans', 'DejaVu Sans', Tahoma, sans-serif

and all monospace fonts with:

  'UbuntuBeta Mono', 'Ubuntu Mono', monospace

I've left "Trebuchet Ms, sans-serif" just to the "launchpad" text near the logo in the headings of {blog,dev,help}.launchpad.net, to respect the brandmark.
