Check out my expert space
I've just filled out my developerWorks Expert space for the first time today. I haven't really added all the feeds and other things I really want to add in but you can be sure I'll be adding more over time. Right now now it is a little self-centered, since that was easiest for me to find. I'll probably move my links and tags to the space rather than push too much into a particular application like this blog.
The point of an expert space is really to focus on a particular individual and the multiple things they may be working on, or the multiple social tools they may be using. This differs from a group space in that it is not shared with others and you don't have to negotiate or discuss what you want to put onto the space (as long as it doesn't break the T's and C's). A group space really is intended to focus on a group activity with several folks who will be active participants in the topic. Think of it this way: in an expert space, YOU are the product. :)
