I herd the WSJ lieks mudkips

From last Friday’s WSJ, a piece entitled _Confessions of an Underwater Homeowner_:

We weren’t oblivious to the fact that people were stretching to buy homes. We were adamant about getting a fixed-rate loan–rates really had nowhere to go but up, so why would we want an adjustable rate? (That line of thinking turned out to be an epic fail–30-year fixed rates have been at less than 5% for weeks lately.)

I wonder what the Journal’s style guide has to say about 4chan-isms. (For starters, isn’t “fail” supposed to be capitalised?)
