When software in the cloud goes sour

Without exports like that, users will become even more wary of storing their data on sites that aren't supported by the "big 5" internet/software companies. There's always the risk the company (or handful of hackers) will go away and take their hard work with them. It's also a differentiator when you do that because the big guys want to hold onto the data.
Obviously an XML dump is not the same as having the full service, but at least, if bad things happen, the users can salvage some of their content without digging through Google/wayback caches.
It is great that you provide the feature (and I'm slightly embarrassed that http://scribbl.net/ doesn't) but what users really need is the ability to get their data after the application has gone down. Not that I see any way to do that given the current state of the internet.
Wufoo have managed to do it extremely well. They provide great export features, and they go to great lengths to explain how and why they provide reliable and redundant infrastructure.
But the good examples will be dragged down by the bad examples, and the end result will be much slower adoption of the model. So, going off-line without warning and without providing a means for customers to get their data, is a great disservice to not just your own customers but to every other hosted application provider.
I don't want to pick on the Stikipad guys in particular, but it's a real problem--if you aren't sure that you'll always be around to serve your customers, you need to make a dead man's switch plan to get the data back into the hands of your customers.
If I lost either I'd be screwed. I'm not so worried about the Goog, but Toggl (and before that 14Dayz) does worry me a bit.
