    TUIR - Command line Reddit

    Most workplaces don't endorse the browsing of reddit while you're being paid to work - in fact, I can't think of any that do.. while that's true, it never hurts to have 1/3 or 1/4 of your terminal assigned to your favorite subreddits out there while you're fighting the good fight. This is an...
