Be interesting.

Much is being said these days about 'how to attract followers' and 'getting people to read your blogs or twits.' This seems a little counter intuitive to me. I approach the whole realm of socializing online with transparency.
Show up. Speak your mind. Read what others have to say, and maybe comment on that if you feel so moved.
Seems fairly straight-forward.
Faking it (posing) is not only a good way to get flamed, it defeats the purpose of socializing. Your content should come from that little place on the inside called you. Your followers should be interested in your message without coercion.
We each have our own unique way of observing the earth and the people that live on it. If, thanks to the cool tech we have all around us, you can share your perspectives with a few folks that find it interesting then bravo. If you have to fabricate the message or the audience, you should probably do something else with your time.
