I understand this might sound weird but I just don't think about fonts. In my head that is designer territory and ever since I realised I was colourweak and couldn't be one anyway I stopped even trying.

I know three types that I use: serif, sans-serif and monospaced programming fonts.

I do however care a lot about keyboard layouts, keyboard shortcuts and general snappiness of the OS so I am definitely a programmer ;-)

Edit: and I'm not a graphics programmer so I'm not an "art dealer" anyway, more like someone in logistics. :-)
