Ok, so there are tools to help me find news feeds. I've played with them for a bit, but I'm probably not going to be using them very much. Information overload - if I want to know something, I prefer to go out and look for it, rather than having the trough of knowledge fill itself automatically.
I've looked at Merlin before, never saw much that I was interested in reading about. Most of the content doesn't seem to be targeted at me... and the way my work schedule tends to happen I don't feel drawn into any particular virtual community other than the one that grasps its claws through the bars of my email client.
