I've noticed that a lot of people are posting messages on others profile pages which is great. However, a lot of them seem to be personal in nature and may be better sent as a private message. I've also had a few reports that people thought profile comments are private - they aren't. I think there is some confusion on where to find private messages, there is a speech bubble icon next to the bell at the top of the page. That is the link to your messages. However, to help people find their messages even more easily I've added a new tab to the main navigation marked "Messages". Please use that link for any message you do not wish others to see.
