Business Insider has not decided what type of media outlet it wants to be.

It tries to combine BuzzFeed, ESPN, GQ, Politico, Food Network, Discovery Health, Bloomberg, and others, and it doesn't quite succeed at any.

It needs to decide what type of news outlet it wants to be. I can't be the only one who notices this.
