This discussion is not about URL shorteners, but rather about the actual URLs throughout the entire Photosynth website being well designed to be human-friendly. My petition is for simple URLs which humans can easily memorize and type without copying and pasting.
In the same way that I make my own bit.ly links memorizable, it is my desire and expectation that every website designer does this for their own site, so that readers and users of that site can type the address of any main page on the site just by thinking of what they want to link to. I am often horrified by websites which are constructed of beautiful looking pages in the main window, but where all the site URLs are long or complicated or ugly. It is just as important for the links to the pages to be beautiful and elegant.
For me, there is nothing memorable about "2a6dd5u". It is, in some ways, even worse than "userprofilepage.aspx?user=".
