Fonts

Hello everyone - I'm new, and have been sifting through the tutorials page, yet I've still come up with a question. What is that pixel font that everyone seems to be using, and where can I get it? I'm jealous, given that my fonts dont look nearly as good. Does anyone have any particular fonts they use on their icons that come out well? Where can I get them? Any feedback would be wonderful.. thank you so much!

xoxo,
Rip
