They protect the reader from the shock of virtual transfer. And fonts are those elements that are so commonly not read. Fonts are closely connected to textual standardization and thus the very nature of the internet. By far still the fundamental computer language used on the internet, HTML and the browsers that interpret it constitute a quantitative structure of exchange that both directs textual or discursive flow, and regulates its dissemination - if that indeed is the manner in which it is distributed. Ebb and flow are governed by specific protocols.
Connection is established according to certain hierarchies.
And like the logic of traditional political economy all elements conform to formal standardization. Computer networks are not a heterogeneity. Computer fonts are an indication of a type of technological complexity that allows for wide varieties of font faces, sizes, shapes, distortions, and types of mark-up. By way of illustration, allow me to compare these two elements. Computer fonts do the same work in the digito-semiotic world that HTML does in the virtual world.
