Name Question of the Day - 7th in the Series

What do you think about middle names? Do you like having a middle name? Do you like some names best with no middle name? Do you think the middle name should fill some special role (i.e. honor someone, use a family surname)? Do you think girls should not have a middle name? Or boys? What about going by the middle name instead of the first name? Do you like that idea or not or not care? Do you think the middle name should 'match' the first name in some way? Or does it matter how it sounds with the last name? Tell me all your thoughts about middle names!
