Side rant: what the heck did they implement on NYtimes.com ?! When I quickly click the text (which I compulsively do to select a paragraph etc.), it changes the font size (sigh)
I am a compulsive selector and I absolutely hate websites that try to add functionality to selections. No, I do not want to share this selection, website, especially when your JS code hangs for a moment as it loads a stupid twitter image.
I think it's some sort of idiotic tap-to-zoom, like for mobile/touch browsers? Since browser zooming is hit and miss, they probably thought they were oh-so-clever. As Raymond Chen says, someone probably got a raise for this.
Running NoScript (https://noscript.net/) in default deny all javascript I can click to select paragraphs without the text doing anything beyond becoming 'selected' text. (Note, I do not normally do this, I had to test to verify.)
