Don't worry, they won't...
Yahoo has bought Tumblr, and idiot boss Marissa Meyer "promises not to screw it up."
Instantly reminds me of a good one-liner from Tom Bergeron on AFV several years ago. Bergeron is introducing a clip in which a teenage dickhead is preparing to jump off a bluff into a rocky creek. Dickhead's friend says "Don't do nothing stupid, dude!" ... and Bergeron interrupts, "Don't worry, dude. He won't not do nothing stupid."
The grammar doesn't quite work out, but the point is perfect. Teenage Dickhead is incapable of NOT being stupid. Yahoo is incapable of NOT screwing up everything it handles. That's their job.
Tumblrites should get ready for new rules, such as
ACHTUNG! Alle Tumblrbrauchr müssen beim Desk von 0700 Uhr bis 1800 Uhr sitzen werden sollen haben kann! Heimatsarbeit ganz verboten! Deskarbeit macht frei!
ACHTUNG! Alle Tumblrbrauchr müssen von TumblrFührerin Marissa Meyr Permission bekommen, wenn sie zum Pissr oder Schittr gehen wollen gehabt sein sind geworden!
