I may still be a little confused as to what exactly is desired here. However this is what I'm going to post. A phenomenal site that I will be referring to for a very long time with the latest in the social media world is http://socialmediatoday.com/. They have the latest news out of the social media world and I will refer to them often.
Another that I as a music lover will use and have used quite a bit is http://consequenceofsound.net/. They have all the latest news from the music world, as well as a lot of great social marketing tools for musicians.
Finally, another site I will refer to (and again, already use a lot) is http://www.last.fm/home. Last.FM can keep me up-to-date on the latest shows in my area and keep me in contact with other music aficionados, as well as tell me what everyone is listening to nowadays. It is a very handy site.
