Building on the concept of a Web 2.0 office suite, Num Sum is an online spreadsheet with tagging and sharing of spreadsheets. Nicely done though still a work in progress.
Combine Num Sum with Writely now all we need is a Web 2.0 Powerpoint application.
What it needs:
* Calculation fields are case sensitive (must be B3 vs b3)
* Adding a new column didn’t adjust the appropriate calculations thereby breaking them.

What about S5? A few more iterations, some Ajaxy stuff and then it is ready.
