I haven't used a lot of it in my day to day work...YET. As I get more and more comfortable, I feel I will. There are a lot of useful Rss feeds that could be very helpful in my job. I will continue to explore. For personal use, I found the blogs and photo/video sessions to be the most useful and fun. As I said, I'm a scrapbook nut and can really get into the whole flickr thing and all!
