After reading the article about what Ning.com did with their information, I was hesitant about doing much at their website. However, I decided to try it anyway. I was surprised to find more depth in the quality of organizations participating. I signed up for it and joined http://neuronetwork.ning.com/, which is a neuropsychology-interest group powered by Springer. I am impressed.
And then I joined the ALA (http://alamembers.ning.com/). I was surprised that they let me in because I'm not a member of all those professional organizations. I am happy that they did, though. I'll have to add another blog entry later after I have the opportunity to participate in the online forums.
