In reply to Workplace Sans:
I'm not especially fond of it myself, if truth be told. As my first ever typeface, it's hardly a surprise if it's less than stellar. Of the three fonts that I've designed over the past few years for computer UI text, this is IMHO the weakest.
But I've got people relying on it now, so I keep trying to polish it into something halfway respectable...
At one point I tried creating a less blocky-looking counterpart, more in the grotesque style, called Workplace Gothic. It was never really finished. However, I've just dusted it off and am starting to put it through a serious overhaul. Maybe it'll be fit for the light of day eventually.
