"About Us"

My work involves visiting different company websites and looking at different pages within the website.  To be able to know more about a certain company, I need to look at the "About Us" pages.  And, sometimes, I cannot help but get frustrated after reading the whole page and ending up not understanding or knowing what the company really does.  I mean, come on, isn't the whole point of an "About" page to inform its readers what the company does or provides???  That's why it is called an "About Us" in the first place!?  

Sorry, just had to rant...  Back to work...
