So, my Twitterfeed strategy - once I have it working as I want - is to move the majority of my network activity to my blog on WordPress, and just every few hours to allow a post to go through to the other social networks, in order to keep up a modest presence there, without spamming everyone.
I don't want to be "owned" by Facebook, Google and Twitter, and for all of my content to be exclusively on those networks. And I want to catch as much as possible of my web activity in one place. At the same time, I want to keep things fairly simple, and not have to worry about complicated relays between networks. I also want to find a single service that allows me read from these networks without visiting them..
