I don't see what the level of writing has to do with whether one is an author or not. You're the author of your comment, and a graffiti artist who draws a penis on a wall is the author of that graffiti. Author merely implies who created the thing.

Anyway, all I was commenting is that I find it quite unpleasant when I write blog posts and people refer to me in the third person, as either "the author" or "the blogger", but between the two, "the author" seems less dismissive and I'd pick that over the other. It's worth keeping in mind that the author probably reads these comments too.

I think the best way to explain our differences is that we have varying preferences for specificity - I like "blogger" because it means "author of a blog post" the same way that I like "commenter" as "author of a comment".

And yes, just because you like the more generalized description of "author" doesn't change that they'll all 3rd person labels, which I'm not sure is pejorative either.
