Not relevant for too many here, but very annoying for anyone living outside the US (like me):
As of today Amazon seems to be directing amazon.com links to the Amazon site of the country that you're in. For example, until now if I clicked an Amazon link on DDMS it took me to the same page as anyone in the US, but now DDMS links redirect me to the amazon.ca page for that product, obviously with a different price and sometimes not available at all. Until today amazon.com and amazon.ca were completely separate (besides using the same login info) but things now seem to link between the two.
Now if I want to order something on amazon.com it seems that I have to go to amazon.com and search for the item. Clicking through any links redirects based on my location.
