I will widen the argument to all the raw movie footage that does not make the final cut. I would love to see all that footage given to fans to make complete remixes of movies.

It wouldn't be difficult to implement, but it would use a ton of Google server space. In order to create case-sensitive search, Google would have to index the words based on the way they are capitalized, adding to the amount of space it would take to store each word and possibly slowing down search. Knowing Google, if they really wanted the feature they would have it, but its not as simple as you would think.  

Awesome!  ;D I really didn't know that existed. This really makes me wonder about other features I don't know about.
That being said, its not exactly what I had in mind. DC is full of really long threads. It would be nice to know which posts I read and which ones I didn't. The new button takes you to the post that was posted after the last time that you looked at the thread. Many times I start reading when there are 30 posts and only read the first few posts which links to a different page and I don't bother to read the rest. When I come back later and discover there are 500 posts I would like to know what I read and what I didn't.

I can't believe all this time the new symbol was a button!
