Julia has to be one of the most likable people in tech! Every time I read one of her articles I feel that same bubbly rush of excitement I got when I was a kid, just starting to unfurl the secrets of reality through my own little experiments. Absolutely lovely.
Yes, it's rare to find someone who possesses deep technological know-how and is also a brilliant teacher and communicator. Andrej Karpathy is another who comes to mind. Fortunately, I've discovered that more people fit this mold recently.
Very much. I'm usually not a fan of the "omg awesomesauce"-style of overexcited blogposts or tutorials, (I much prefer the drier, high signal-to-noise ratio, concise, beautiful texts of the Landau&Lifschitz style), but her posts all make me feel that giddy rush of excitement you're talking about :)
