Typekit has gone from invite only to open registration.
What is Typekit? Think of it as YouTube for fonts. With it you can consistently display non-standard fonts on websites. Previous solutions haven’t been as easy to use, nor have they been as respectful of type foundries’ rights. Despite a (currently) somewhat limited amount of fonts from which to choose, Typekit is win-win.
Take a look at “Attention font nerds” above. It isn’t an image. You can copy the characters. They’ll be indexed by search engines and be read by screen readers.
A word of caution
Typekit might let us express ourselves more effectively on the web but it could also lead to some ransom note looking pages. Please be responsible with Typekit. When in doubt, limit your font use to one serif and one sans-serif per page. Use size, color and weight for emphasis.
