Imagine a typo so bad it renders the tweet unreadable aloud for a chunk of the population.
This is that typo.
It took awhile for them to fix their mistake, but when they did, they cried "spelling error," rather than typo.
A spelling error is forgetting that it's "I before E except after C," which still makes it the same word.
This is a different word.
Our thoughts and prayers go out to Yahoo Finance's (now former) social media manager. Get extra drunk this weekend.
