if you've signed up and logged in to Technorati and have claimed your blog on Technorati, when you go to their ping page you will see that against the name of each claimed blog it gives the number of days or hours ago that Technorati last indexed or crawled your blog....Remember you won't see that info unless you've both signed in AND claimed your blog.)
