Google indexes pasword protected pages

Sometime back Google had brought a company called Transformic inc. which worked on  indexing password protected pages..They have been working with Google engineers  in unifing their development with google. And google can now index password protected pages.

It works something like this when it finds forms < form > it seams it performs a.small number of queries using the form. For text boxes, it automatically choose words from the site and for select menus, check boxes, and radio buttons it chooses from  the values of the HTML.

Does this spell doom?  Not actually. This is a great thing . There are a lot of forum that have great content but are password protected hence we never get those sites in our search result. now with this we will be able to visit those sites . we still may not be able to read the content without actually logging in but get some ideausing cache pages
