I agree that lots of random sharing data can be useless, but I think it is only useless in its current form. There is a great deal of data to be intelligently mined there.
For example, I wish Facebook told me aggregate info, like 12 of my friends are reading X book, and 15 listen to Y song, and 5 have liked Z restaurant. To me this is a lot more compelling as I can see real trends in what my social circle is consuming.
