Help on Social Media Networking

I need some thoughts and opinions on social networking to make the best use of my time.  I have Facebook, Ravelry, Pinterest, Blog, and now Google+.  Which do you prefer and why, which works better for crochet news and info, friends and family??? What kind of results have you seen  from using Google+?  Is having a Twitter account worth it.   Please leave comments and CHECK THE NOTIFY BOX this will allow you  to see my replies.   Thanks, my bermuda triangle of time is no longer three (FB, Rav, Pin)
