For those unfamiliar with Typekit or font replacement, the advantage is this: services such as Typekit make it possible to use fonts that otherwise might not be available. Previously, there was no way to know if a user had a particular font installed.
For example, a website designer chose to use the font Museo Slab (pictured below) for a heading, rather than Helvetica. The Museo Slab font may not be installed on a user's computer and, as a result, the viewer would see another, more-basic font. The beauty of a service like Typekit, is that these “special” fonts are stored on a server, and then displayed to any viewer when a site loads. This means users are going to see the site as it was designed.
So what does this mean for the future of typography on the web? Well, quite simply, it means user experiences can only get richer. By having a wider array of typography available to use, website design companies can create visually pleasing websites without sacrificing search engine optimisation. For example, where designers may have had to use images for titles or headings before (in order to produce the most-aesthetically pleasing visuals), static text can now be used.
It's interesting to see where this feature takes web design trends in regards to typography on the web. Still, we must remember that technology changes all the time – and just because we have the ability to use hundreds of fonts, doesn't necessarily mean that we should (at least not all on the same website or page). As Brian Hoff of The Design Cubicle stated, "With beautiful type comes great responsibility."
