profile hoverbox inconsistency

hey guys,
it would be a good idea to have a consistent behaviour throughout the site for displaying the profile hoverbox and not random as it seems to be now. examples:

stream
in a stream of the type "link" when you hover over the name the hoverbox is showing up, on all other streams there is no hoverbox. so is there a special reason for this one type to use hoverbox while on all other streams it's not used?

friends/followers
in the widgets for friends / followers / following when hovering over a user the hoverbox appears, for the suggested friends widget it doesn't...
also when you view the friends / followers / following page (instead of the widget) there is now no more hoverbox...
