Gotta say, wasn't that interested when I clicked the link thinking "yet another programming font". I must have 30 or so installed and yet still end up using Consolas (mostly because it's the default in my IDE and I've had to reinstall a few times this last year).
I will say, though, that I have always hated the traditional "a" used in fonts, preferring the more simplified one that's typically used in handwriting, so I was pleasantly surprised to see that it was one of the very few that use my preferred style. Yes, it can be ambiguous with the "o" character (though this has never been a problem in practice with the font configured even at the small sizes I use) but I find it more ascetically pleasing for whatever reason.
