I had been SEO enthusiast for some time now. As a part of my work working as wordpress web developer, I had to update myself with the latest trends on the SEO. While I do read a lot on various blogs, one of the author I admire highly is Matt Cutts.
Matt Cutts, videos and blog had been an awesome source for me understanding the concept of SEO and specially the On Page SEO.
Browsing around the web I found a site dedicated to Matt Cutts, name The Short Cutts, which lists all the videos recorded by Matt and provides the precise answers to each video. The site is really awesome and worth checking at.
