Handwriting fonts aren't new, but a free online service that changes your handwriting into your own personal font is new. YourFonts will take your handwriting from their PDF form and make a screen-friendly font.
Screen friendly, this new font won't print unless you upgrade. Another fun use would be to create your personalized happy faces, hearts and frownies.
Implications - Ever since chat rooms and programs have come about, people have really emphasized the importance of changing fonts as a form of individuality. It's easy to make a mark in the online world with unique usernames and frequenting forums, but perhaps there's still a need to establish oneself by customizing fonts just to add that little spice of personality that makes you stand out among the millions who surf the web everyday.
