The internet moves ever onward. As many of the commentators are beginning to point out, we are moving inexorably towards a point where storage of data and computing power are essentially free.
The fact that developers are being offered storage at this sort of price indicates that we will see more and more things being stored all over the place. Why store something on your PC hard drive, where it is vulnerable to corruption when you can store it online too?
Apple's time machine product has shown that consumers can see the benefit of having a well designed backup solution. I suspect it won't be very long before we'll be seeing a similar product that backs up your data online and then serves you adverts based around the content that you are uploading.
As with all other products along these lines, we will be seeing some people moaning about their loss of privacy. However I think the majority of the population will be willing to sacrifice privacy for ease of use.
I would be willing to put a bet on that we will see a consumer friendly version of time machine appearing on the internet reasonably soon. The question is how deep they'll be willing to go with their profiling of users.
