There are fonts to love, and fonts to hate. The Helvetica (and its clones like Arial) is clearly one of the latter.

This sans-serif, designed in 1957 in Switzerland, may be clear and readable, but it has lost all of its character through over-use. It resides on virtually every computer, and has become a de-facto standard in signage.

It also made its way to "corporate identities" of all kind, offering however an "identity" which is as bland as can be.

Helvetica can be seen everywhere around us; you can't escape it; this previously unseen evolution to typographical homogeneity is just one more negative aspects of globalisation.

This "Helvetica lifestyle" is a clear threat to individual, typoghraphic, artistic and intellectual expression.

Besides the practical reason that nearly everybody got it on their computer, I can not find any good reason ever to use this font.
