It has been a LONG time since I checked in. Glad to see the old gang at it still.
I've been asked to evaluate Ecofont, and am coming up short with actual data, or even anyone saying they use it. http://www.ecofont.eu/ecofont_en.html
My thought is it's gimmicky, and the same thing could be accomplished much more easily by:
Printing 25% fewer pages
Writing 25% fewer words
Make the font size 25% smaller
Use lightweight fonts, Don’t use bold anything.
Set your font fill color to a 75% black.
But I need to give a fair assessment to well-intentioned people. Does anyone have even anecdotal experience to share?
