The name grates on my nerves (although I am aware of the URL shortage problem). But the product looks cool. I'm going to use it for a few days and see how I like it. It looks near perfect.
Also, I have no idea how this is a business, but I've resigned myself to being thoroughly confused by Valley business sense. I imagine you will be no more or less economically successful than simplenote.
As a business, I think we'll follow the lead of dropbox and evernote. Some variety of:
1) You get a lot for free.
2) If you need even more (or just love us) you can pay us (My hunch is we'll also have an easy to find "I need a lot of space but am poor." option)
3) You can always earn more space by promoting us
Also, once we have collaboration this could be a pretty powerful enterprise tool, and businesses pay lots of money for software.
