The style on the wiki:

@font-face {
  font-family: 'Lato';
  font-style: italic;
  font-weight: 700;
  src: local('Lato Bold Italic'), local('Lato-BoldItalic'), url(http://wiki.mediagoblin.org/skins/mediagoblin/fonts/Lato-BoldItalic.ttf?2011-11-02T15:46:40Z) format('truetype');
}
@font-face {
  font-family: 'Lato';
  font-style: normal;
  font-weight: 400;
  src: local('Lato Regular'), local('Lato-Regular'), url('fonts/Lato-Regular.woff') format('truetype');
}

The last line should probably be:

src: local('Lato Regular'), local('Lato-Regular'), url('http://wiki.mediagoblin.org/skins/mediagoblin/fonts/Lato-Regular.woff') format('truetype');

Right now all browsers show the wrong font, because noone can get the Lato-regular one. However, it does look worse in Opera, because Opera chooses to display the italic font instead of the bold, whilst the other browsers bolds everything.

Well, looks crappy in all of them, but you can see it's wrong easier in Opera ;-)

Multiple places throughout the application don't have very nice or descriptive s. For example:

• http://mediagoblin.com/u/cwebber/ should have "cwebber's profile" in the title
• http://mediagoblin.com/u/cwebber/m/fear-of-flight/ should have "Fear of Flight" in the title
• http://mediagoblin.com/tag/creature/ should say "Media tagged with 'creature'"
• http://mediagoblin.com/u/cwebber/gallery/ should say "cwebber's main gallery" (or something less shitty :))

Thumbnails for some images, like http://mg.wandborg.se/u/abner/m/fdfs/ have a tendency to look ugly when transformed to JPEG, http://i.imgur.com/QM0sw.png.

One way to remedy this would to save PNG image thumbnails as PNGs.
