Writing is a individual practice (mostly).

I think writing is mostly an individual practice because most writers write alone. Most books are written by a single person as opposed to more than one person. Not to say this doesn't happen, of course it does, but the majority of things written have a single author. Many writers write alone because there are less distractions. I always associate writing with being alone. My generalized, stereotypical construction of a writer is an introvert. This isn't always true just as stereotypes in general are never always true but when I think of writing I never imagine big groups of people sharing ideas (though I know that happens). I would also say writing is typically an individual practice because a lot of writing is self reflective or invented from the imagination of an individual. Many writers think of their writing as a valuable possession. Again not to say writing can't be a social practice but in general writers tend to write alone.
