Diva, Expert and Observers

A definition for me being an online person,it's not that clear at all because I don't think any of them define me,and at the same time I am a little of each one. I don't like to be the central attention in the social media all the time or post inappropriate stuff in my pages to get more attention than others. Expert also doesn't define me because I don't speak only occasionally, I speak and give my opinion the most of the time but just to express myself,but a definition that match with me about the expert is that I'm happy to answer any questions,inquires and give advices. Also I'm an observer but when I have to give my comment in a social media I don't complain about it.
