More likely than not you are viewing this site on a Windows PC. If so you will notice the banner above uses Arial. Arial is rip clone of Helvetica a timeless classic that is by its very nature expensive to license. Microsoft knows its customers, these are the people that laugh at ‘hilarious’ clip art and think using Comic Sans gives them ‘personality’. So MS hired Monotype to make alternatives to all the popular postscript type faces, including Helvetica.
I hardly ever get to see the real thing, so its very nice to have the differences pointed out.
Arial is like Helvetica’s unfortunate twin, that through some accident got a few scars. Still retaining the general beauty, but not nearly as impressive as Hell-uva-tika.
