Facebook is requesting that its members declare if they are male or female so it can correct a grammatical device that causes the site to refer to users as "they" or "themselves."

Grammatical errors in the messages Facebook uses to personalize pronouns when members communicate with their friends have increased since the site launched in other countries that do not speak English.

When it comes to social networks, a new study shows that men are more likely than women to downplay the first part of the term.  Women, according to Rapleaf, tend to have deeper relationships and a greater number of friends.
