The thing is, on Facebook if you post something it may or may not appear in a friend's stream. If you know of a specific person who would benefit from seeing something, at-ing that person makes sure that they see it. Maybe Facebook should add a new field to signal that someone would be interested or hide @mentions of other people in comments, but you can't really blame the user for this.
The bigger crime is that there's a perfectly good permalink for every FB post, but nobody seems to use it to reference content, when @-ing a friend is easier, quicker, and supported on every client.
