Loving the sparks feature, and I had a random guy add me to one of his circles, and my only thought why was that he looked up people with my job description. I thought that was pretty cool, and it could definitely be used as a job networking tool. There are just so many things better about Google+ over Facebook that I'll never go back to Facebook. Once they open this thing to the masses it could be huge, but it seems like it's taking forever. I'm now getting all my news on topics I'm interested in via the sparks feature which is great, it will link to news articles, youtube videos etc. etc.
