Smartsheet.com, a Bellevue-based "Office 2.0" venture that provides online task management and spreadsheet services, launched version 2.0 yesterday with more features for users of the free version.

(I mentioned the company in a recent column on Google.)

The company also announced that its free online document management service is being powered by Amazon.com's S3 storage service.

Additionally, the company has plugged in Amazon's Mechanical Turk labor service, so Smartsheet.com customers can tap the Turks to build new business templates.

"We extended the document feature to all Smartsheet customers so that anyone, free or paying, may experience the speed and reliability of Amazon S3,'' Mark Mader, Smartsheet.com president, said in the release. "We've also expanded our use of Amazon Web Services to include Amazon Mechanical Turk. This is a great way for us to cost effectively tap into a diverse workforce for the identification of business and consumer content."

Maybe Amazon ought to buy Smartsheet and take the fight to Google Apps.
