Yahoo Site Explorer seems to have pushed out their beta design to everyone now. The new look, is not just visual, it also contains these new data points:
+ Site URL + Number of pages known + Number of pages crawled + Number of host on this domain + Number of inlinks + Number of inlink domains + Number of outlinks + Number of outlink domains
Patrick at BlogStorm took notice to this update early this morning. Yes, it is now available to everyone to see by default, without having to go to the beta URL. Nice catch Patrick.
A DigitalPoint Forums thread has a poll on if you like the new design or not. I am not sure if the poll is fair, because the new design not only gives you a slightly new look, but also gives you new data - which everyone likes.
