How do you guys feel about this? (taken from the Data Liberation Front's website which was linked at the beginning of the article) "...we always encourage people to ask these three questions before starting to use a product that will store their data: Can I get my data out at all? How much is it going to cost to get my data out? How much of my time is it going to take to get my data out? The ideal answers to these questions are: Yes. Nothing more than I'm already paying. As little as possible." My problem with it is that there IS a cost to exporting this data. That cost has to be paid by someone. Is it fair to work that into your price when it's a feature that perhaps very few users might actually use? How often should you allow users to back up their data?This is mostly in the context of SAAS products that are not free.
