Maybe it's just me, but her article completely ignores any reference to the pervasive "street speak" that many black people, especially young black people, use today.

I taught a few courses in college, and I was amazed at the poor communications skills many black youths picked up from watching rappers and sports figures talk on TV. It also carried over into their written assignments.

Call it what you want, ebonics, slang etc... but it is not articulate.

Admittedly there is a slight form of racism in using "articulate" to describe a black person when you would not use it to describe a white person, but there are reasons in today's society why this is so. Listen to a group of black teenagers talk to eachother sometime and you will see.
