NumSum
NumSum is a decent spreadsheet that lives in the Internet Cloud. That means (duh!) your spreadsheet is available anywhere you have Internet access. Yes, it is FREE. Not sure what happens to the NumSum folks once Google or Microsoft roll out their office tools online. Maybe they’ll ‘splain it to me.
Or maybe I can read the NumSum FAQ:

What is Num Sum?
We’re a web site that brings you online, simple, sharable web spreadsheets.
What’s a social spreadsheet?They’re spreadsheets that are easily shared with your friends, relatives and co-workers.
And, because they’re social, it’s also easy to find like-minded people working on the same kinds of spreadsheets and information as you.

So how does Num Sum make money?Just like everyone else. Text-based advertising (yes, it’s coming), and the aforementioned paid subscriptions..
