And I'm Supposed to Learn.... What?

I'm beginning the first session of an online Creative Writing Course that goes over the basics of setting, narrative, character building, etc. I've really been looking forward to this class; I need to get the creative juices flowing and stimulate my inner "muse". I just logged on for the first session, and the instructor left a note on the discussion board, welcoming us all and reiterating briefly the objectives of the class. After her welcome, several participants had posted introductions of themselves. After the first group had posted, the instructor had posted a response that included, "I'm soooo looking forward to your assignments. ....".

Now, I realize that this particular form of speech is popular recently, but that doesn't mean I have to like it. What, exactly, am I supposed to learn from this person? In her introduction, she states her children are grown, so she's a mature woman, presumably with writing credentials since she's teaching this class. Am I learning the definition of "sooooo" and when best to use it here?

I also recently purchased a book that deals with bringing characters "to life". The THIRD SENTENCE states: "After pouring through the recently published books in each subject, ..."

I know I'm a grammar snob (my husband reminds me all the time when I correct him for saying, "we shoulda went there") but really. What exactly am I learning here?
