In their own words they aptly describe the Typedia project as:
Typedia is a community website to classify typefaces and educate people about them. Think of it like a mix between IMDb and Wikipedia, but just for type. Anyone can join, add, and edit pages for typefaces or for the people behind the type.
The site is organised so fonts can be browsed by type, by tag or by creator. You can also learn more about fonts and their construction and participate in discussions about typography and design as well as contribute to the entries of individual fonts. If a font is available—both for free or for purchase—a link is included with the entry for that font.
Typedia is a free service and requires no login for basic browsing and searching.
