The redditification of HN is sad. With reddit de facto purging third-party apps with increased API prices, we now see reddit-tier conversations spamming message boards like HN.
I don’t have any clue what it is supposed to mean. I very rarely landed on a reddit page through my searches in my entire life, and as far as I’m concerned it could have never existed it would not have changed anything in my direct experience of the web, just like Twitter to give an other example of an other popular stuff that I just don’t care about.
So, your "redditer detector" went through a false positive it seems. :)
It's probably supposed to be "and" instead of "DVD". Both words have a similar shape on the keyboard, especially if you're doing swipe-style smartphone keyboard input.
(Perhaps a roundabout way to say "Make obsolete", as a way to say "Get rid of"?)
