SEOmoz is offering a paid service: Linkscape. As far as I understand, they have copied most of the web, created their own index and link graph so they don't have to rely on search engines for this valuable SEO information. Sooner or later this was going to happen; after all, this information is part of the Internet. It's a great idea and business too. I've just tried their free Tool: Linkscape but I will definitely try it for a month at least.
yes that is a cool tool, but what is more interesting is how i can block their bot's from my site's robots.txt file.
