confused in setting up

Hi ,

i am old to wordpress single installation ..and i have tried mu long back ..just checked and it seems to be much changed

I have seen the installation instructions and all …and i can do that

what i want to ask is :

– is it better to install buddypress in to single wordpress ? will this gives user a ability to create his own blog and all?

– Or is it better to install buddypress on multisite

my requirement is that i want users to register , make friends , create a blogging , earning thru revenue sharing and all …

i am sorry to ask such silly questions ..but i am very new to mu and buddypress as well ??
