Google has acquired wiki service JotSpot for an undisclosed sum. 

A wiki allows multiple users to add, remove and edit content, and programmers or writers to collaborate online. The technology is best known through the Wikipedia online encyclopaedia.

JotSpot sells premium services to businesses, but has dropped its subscription fees following the acquisition.

Even though Google focuses mostly on consumers and individual users, JotSpot co-founder Joe Kraus claimed in a blog posting that the acquisition was a natural fit. 

"As we built the business over the past three years Google consistently attracted our attention. We watched it acquire Writely, and launch Google Groups, Google Spreadsheets and Google Apps for Your Domain," he wrote.

"It was pretty apparent that Google shared our vision for how groups of people can create, manage and share information online."

"Joining Google allows us to plug into the resources that only a company of Google's scale can offer, like a huge audience, access to world-class data centres and a team of incredibly smart people."

The software is currently being moved to Google's architecture and JotSpot will not accept any new sign-ups during the migration.
