Serif vs. Sans Serif on the Verge

Can you change something here? When commenting on a post, the font will be Serif (Adelle). But when we hit post it will be a Sans Serif font (system's default serif font; Mac - Helvetica; Windows - Arial). Can you change it where it will be just Sans Serif or just Serif. This is just something I just noticed and it annoys me a little.

Edit: Fixed what the serif and sans serf fonts by what azulum said.
