Hey guys no need to worry about the Inlinks in site explorer. From now onwards keep an eye at Bing Webmaster tools because Yahoo! search algorithms has been merged into Bing. yahoo! stated that "Webmasters should now be using the Bing Webmaster Tools to ensure that their websites continue to get high quality organic search traffic from Bing and Yahoo!." have a look at the Yahoo's official note regarding the transition of their algorithms and all: http://siteexplorer.search.yahoo.com/index.php
Inlinks are nothing but the pages in your website (which were crawled by yahoo). however, no need to think of site explorer now. Because yahoo's search algorithms has been merged into Bing Search engine. So, just concentrate on Bing webmaster tools. For details, please refer to the official yahoo site explorer's website: http://siteexplorer.search.yahoo.com/index.php
