Almost nobody has heard of Less Wrong or Eliezer. There's a mean article on RationalWiki (though honestly it doesn't look that mean anymore), there's a hostile thread on DarkLordPotter, but almost nobody has heard of those, either. This was even more true two years ago.

I'm not wedrifid. But I suspect his point is that, outside of a few incredibly narrow sub-sub-cultures, nobody knows anything about Less Wrong and no one who knows you personally will judge you by your connection to it, no matter how public or overt.
