The League of Movable Type is championing the development of free, open source typography for use on the web. I have found their blog to be a good resource for font development.
The League has been around a long time. We started it back in January of 2009, back when browsers were just getting the ability to use custom fonts on pages, but no font foundries were allowing their fonts to be used.
This was before Typekit. Before Google Fonts. Before WOFF, and before icon fonts or bulletproof
@font-facesyntax. There were a few open-source fonts sprinkled around the corners of the web, and we knew the web needed more.
