As eWEEK [officially ;-)] reports, Microsoft "is readying an online marketplace, code-named Fremont, which is apparently in response to a similar feature that rival Google Inc. introduced a few weeks ago."
It's true. Microsoft saw that Google was introducing a new product and immediately re-tasked several hundred software developers to work day and night building a rival product.
Before Google introduced Base, Microsoft wasn't planning anything. Fremont didn't even exist. It was absolutely 100% completely in response to Google.
Microsoft is just that agile.
