Today marks the 30th anniversary of VisiCalc, the spreadsheet that sparked the PC Revolution. You can read on Dan Bricklin's blog the evolution of the spreadsheet from then to now, the day Socialtext took SocialCalc out of beta.

During the beta period we got some great feedback that led to improvements like better handling of revision history cell-by-cell. We also discovered use cases we didn't anticipate. Like how Epitaph Records manages and collaborates around their release schedules. Or how Meredith Corporation works across organizational boundries for cross-marketing:
"I used to get 10 e-mails a day from different people with these reports," said Dave Ball, Meredith's vice president of consumer marketing.

It helps us distribute information and knowledge faster, so we can react more quickly."
