I sort of feel a lot of celebrities don't really connect with their fans these days by doing more autograph signing, affordable concert tickets, and meet and greets.
In a way, they use Youtube, Twitter and Facebook to connect with friends all over the world, but it does not feel very personal.
I think some celebrities do, but most don't give a crap about fans.
To those who do care, they do stuff to keep in touch with their fans, and it isnt just for publicity. For example, Milla Jovovich uses twitter to discuss the new Resident Evil movie to her fans. I get the vibe she does care and wants us informed.
But if you look at other people, like music stars and actors like Megan Fox. Do you really think they care? They just want the money that comes with fame.
