Deliberately building out your social network at work

I followed an interesting article in Time's Detroit Blog (If you have not followed this yet, make sure you check it out at http://detroit.blogs.time.com/ ) and it brought me to here! I recently started a video blog on the topic of personal and professional development and I see the topic of networking is quite popular here. You can find my video at the address at the bottom. I would really like to hear your thoughts and reactions to it as well as any counter arguments! Thanks!
