My dream social netwok

I would like a social network that could have something like facebook has,for example:The capacity of sharing pictures and videos that I like or about my life. Another thing that would like could be to find out about the news of many topics that interest me like politcs,music,ect...

In addition; I would like that the social network could notify me about what happen in the life of famous people  and know about future events in our city like parties and concerts ,and to be able to download my favourite music without paying for it, and the last thing would be the possibility of could know who is seeing my profile pictures.
