Depends on what kind of attention seeker. You have those that are completely empty. Have no personality worth mentioning and have nothing to say, and try to make up for that by acting just in such a way that they get everybody's attention... mostly in a negative way. And there are those that put emphasis on the fact that they aren't like everybody else and have a need to express themselves and their thoughts (that might very well matter and/or make a difference). I think I kind of am the latter.
