I disagree. Many people have excessively long profiles, that only change infrequently. There's no need to see these things every time you mouse over their name. Furthermore, any links in the profile would be unclickable, so to get the most of the profile, you'd have to open up the get info panel anyway.
I too think this is much. Some people have long enough away messages that make my tooltip extend to the whole length of the screen. I really don't need their profile there too (which is less changing than the away message, and probably why it is currently inaccessible from the tooltips).
