I use "guy" generically, I don't read content with gender in mind unless it is pertinent. She did not express a preference (or I missed it).

You missed it!

If you're going to comment on someone's article, and their blog has an "about" page, read it before leaving the comment. It's baseline etiquette.

She's not an it, either.

That's true. It's less wrong; and my intent was to add a bit of fun. Sorry, guy.
