That's just wrong. These are talking points and are the basis for your "experience", which is important to discuss.
> Enrich your resume with numbers and accomplishments. Instead of ‘Was building a web application with [X] and [Y], write ‘Led the development of [X] feature, integrated it across [Z] products, resulting in extra [Y] in revenue’.
You probably don't know the revenue at a company of any scale larger than 10 people. More importantly, these numbers likely mean nothing when applying at a different company (even if it's the exact same position in the same industry).
> Omit the Summary and Objective sections. In 9 cases out of 10, summaries and objectives are not impressive.
It's not supposed to be impressive, it's supposed to be informative and a talking point.
> Use modern fonts.
Use courier or some other common plain text fixed-width font. Format it as if it's being read like that, since someone may have to print it out and hand it around and maybe gasp copy-paste it (like web forms and other large-company-process-nonsense) in an intermediate form. Don't be an ass.
Having interviewed hundreds of times and been interviewed hundreds of times (I keep lots of resumes), I would not recommend this blog post as a guide.
