Robin Good: According to Klout there are at least 16 different types of online influencers, ranging from those who love to actively share and participate, to those who more quitely like to explore, observe and report.
The Klout Influence Matrix identifies these specific 16 types:
Curator Broadcaster Syndicator Feeder Tastemaker Celebrity Thought Leader Pundit Dabbler Conversationalist Observer Explorer Socializer Networker Activist Specialist

As in my case, you may likely feel that you belong in more than one of these categories.
What matters is your ability to develop greater sensitivity for the differences that make up these profiles and to cull more attentively those that you feel are closer to your character and objectives.
