I read that page and looked for the reason I don't use Conda (because I already have virtualenvs and I'm not prepared to burn them all down):

Doesn't sound like much of a myth then, if Conda's take on virtualenv is "you can technically do this, but everything will break ungracefully and unrecoverably, so please don't".
He's not saying that you _should_ install conda within a virtualenv, but that some have tried with some success.
At the end, one of his conclusions is: "If you want to install Python packages within an Isolated environment, pip+virtualenv and conda+conda-env are mostly interchangeable". So don't change if you don't have to.
But he does give reasons why conda may be superior to virtualenv -- managing different version of Python, tracking non-Python dependencies, true isolation of environments, etc.
