This thing called Writing

Defining writing has often been the topic of debate in my classes. Is it strictly putting words down whether digitally or physically writing them, or is it more than that? While I wouldn't go so far as to say that what we choose to wear or facial expressions and the like count as writing, I do think they count as communicating, which I think is how they get thrown into the mix of what is writing. Writing to me has to be in word form whether digitally or otherwise. However I do stand in opposition to those who say that the little things we write, such as status updates on Facebook or twitter, do not count as "real writing." They are every bit as much writing as anything else as they are still communicating something in word format. Another blurred line is design. I do think that this is invaluable in regards to communication (the psychology of colors and other design aspects just can't be ignored in terms of communicating) however whether they could be considered "writing" is still something I have to decide upon.
