I studied the Lorem Ipsum (thats why its there) and the "es" doesn't look so hot either next to each other. Or was that "se" hard to tell.
The designer should be proud that the worst problems that can be found by picky people who stare at screens for 12 hours a day are relatively minor and easily fixable. Its a good programming font. Once its an "apt-get" away (and what are its licensing terms? I must have missed that part) I'll probably deploy it and use it.
I really like the m, not fuzzy and I can tell right away it's an m. To me it's not so important how pretty it is as much as how easy it is to tell what is what. Lower case k looks really good to me too, too often that and lower case h are sort of fuzzy and hard to distinguish in small size.
