Social Media aggregators and interaction computer - smartphone, where to look to manage your digital life?

For few weeks now I want to take some time to think about the organisation and the flow of my information. I have Facebook for my friends, Linkedin for the professional, Twitter for the social media and monitoring related. Then you have my StumbleUpon that I use like the library of my favorites that I tag.

After that you have 3 emails adresses, a blog where I would like to be more active, a Flickr and a Picasa... I also belong to two networking groups, one on Meetup, another one on a forum.
And well that is not that much...
So what did I do?

I looked at aggregators of social media.
