A Digital Presentation I Would Like to Make - The Rosetta Stone and Hieroglyphs

In hindsight, I suppose the various blogs I made commenting briefly about the sites I made use of for my presentation of the Rosetta Stone were leading up to this decision.

While a number of the sites I looked at did present general information about the Rosetta Stone, that is about it.  They rarely go into the Rosetta Stone's history and cultural significance, and primarily focus on its discovery and its use in the deciphering of Hieroglyphs.  

What does the text on the Rosetta Stone say about the time it was written in?  What is its current cultural significance?  How did the Egyptian language become lost?  What does the Rosetta Stone's successful deciphering tell us about Egyptian Hieroglyphs?

These are a number of questions that a number of the sites I looked into passed over.

Of the sites I looked at, How Stuff Work's "How the Rosetta Stone Works" was the most thorough in the information it presented on its subject, explaining its history and even the political significance of the Rosetta Stone.

However, I believe it could be done better.
