After finishing up some recent work on Illustrator which included some lettering, I came to the realization that I am really sick of pretty much every font. Luckily, a friend of mine was around to show me FontStruct, a site with simple and intuitive editing functions and block templates which allow you to create your own fonts. Even if you don't have the time or inclination to design a full set, you can still mess around with the editor and browse other users' creations. Obviously, you can save, export, and do all sorts of other things one would normally expect to be able to do with an editing program.
I give it an unqualified 7/10 on the time wasting scale.
