That can be fixed with this:

  body {
    font: normal 14px/18px verdana;
    color: #333;
  }

From my quick read, the article talks about the proliferation of "creative technologist" who lack deep technical skills, and the problems brought when these people is put in charge of conceive, and lead the implementation of creative technology projects. I agree with their point.

I wish I could say something else, but I have to agree. I did think the exact same thing.

There are people who like old school and people who don't. Where's the point in discussing about taste?

It isn't taste. That font is barely readable. Worse, their encoding wasn't UTF-8, so a lot of their punctuation showed up as black rectangles, darker and solider than the text. I had to fight to keep my eyes from skipping from black block to black block without reading the spindly gray text in between.

It's not about taste, but about readability, a part of usability. Why act like a technologist while flushing about 50 years of usability knowledge (Helvetica is from late 50s) down the drain? Heterospaced fonts with significant contrast are used widely for good reasons. Ignoring these harms credibility of the writer severely, at least for me personally.
