Social media is evolving very fast. I am not sure if you were following a new site called "pinterest". It was very popular for a while, it may still be, but it is fading. Still popular with certain demographics, mostly females.
Now we have this "Branch". Just like Google+, yes I am a big fan of Google+ the Branch let's you focus. Right now there is only you and I on this conversation, but as we grow, and we establish a following, we can invite other people into our conversation.
There is also Sulia. Check it out! Sulia is also a more focused conversation, but not by individuals, but by topic. Personal Finance is one topic. We need to write credit repair stuff under that topic.
