That's commonly referred to as Kerning: http://en.wikipedia.org/wiki/Kerning

I find that the biggest problem with the font as well. For a monospaced font, it doesn't look all that monospaced. Many of the glyphs have odd positioning. It gives the font a look of activity or "fun-ness" that doesn't match well with it's intending purpose as a coding font.
