I just finished creating my latest preso 50 Sites in 60 Minutes V. 3. This is a collection of sites that I like to use in a 1 hr session of professional development. Also, I like to update it twice a year to keep things fresh and because the first two were such a huge success. The last volume received over 21,000 views on Slideshare alone. As w/ all my resources feel free to use them anyway you see fit and I hope you enjoy it. I've even seen this used as teaching tool for a blogging exercise at the college level. Stay tuned for volume 4 sometime this summer!!!
