Career

The most beneficial thing to my career has been to practice sport on a regular basis. Way more important than reading news about technology ! It improves little by little.
The most detrimental is procrastination. It strikes unexpectedly and it is harmful in very different ways. Once, my back hurts so bad that I was stuck on my couch for 2 month. 

LinkedIn groups for social networking

I am starting to use LinkedIn and Ning to build some social networking sites. I find the state of these tools a bit lacking. OpenSocial had some big promises. Yet, there are less than 10 applications on LinkedIn and nothing for groups.
LinkedIn made it clear : There are no Applications available for groups.
Ning looks great at first, but it has some strange limitations. For example you cannot rename a post: you have to create a new one, copy the text and delete the old one.
There are good surprises also: the collaboration between Apec and LinkedIn is a big plus.
