Has anybody else noticed this?  I have spent the last several weeks doing the excruciatingly hard work of trying to build quality inbound links to the MailCase website.  When I check Yahoo site Explorer, a lot of the links show up right away.  But in Google's webmaster tools, these same links are not showing up as much as two months later.

I have reason to believe that I am getting credit for the links in Google because MailCase is steadily moving up in the rankings for my primary keywords.  What I think is happening is that Google is giving me credit for the  links, but not showing them in Webmaster Tools.

The word on the street is that a lot of the data in Webmaster tools is pretty crappy.  I guess this must extend to backlinks too.  I would love to hear from anybody out there with a similar problem.
