Managing your social networks (how many do you belong to)?

I don’t know about you, but I can get overwhelmed sometimes (okay, a lot of the time) when it comes to networking especially belonging to 13 social networks.  No, that’s not a typo.  I belong to 13 social networks (see below).  Using them to meet new people with common interests and to maintain existing relationships/friendships is, although fun, VERY time consuming.  Before I know it, I’ve been on my computer for hours (headache from staring at a bright screen and hand cramps from continuous typing included).  Just when I think I’m finished and am about to log out, I still have to link up my most current blog post.  I’m tired just thinking about it.  Wouldn’t it be nice to be able to copy your blog post url and paste it into a message that, once sent, would get distributed across all of your social networks at the same time?  You know, sort of like magic.  You do believe in magic right?  Well, I certainly do which is what prompted my search for something that would, for the love of God, help me do just this!
