Chrome users may be interested in a new browser extension called PokeGone:
Remove Pokemon from the Internet!
Sick and tired of hearing about Pokemon? PokeGone will take care of that! This extension will stop your eyes from seeing grown adults raving on about Pokemon - simple as.
Remove all traces of Pokemon from the internet with one simple extension!
Unfortunately, there are mixed reports of PokeGone's ability to "catch 'em all" - so it may be that you find it an ineffective way to filter talk of Pokémon Go from your screen.
This was a public service announcement.
