Google acquires EtherPad online collaboration tool
The Net colossus is bolstering the Google Wave project by acquiring AppJet, a smaller rival with an online collaboration service. EtherPad will shut down in March.
Google, probably the most prominent advocate of moving traditional productivity software such as word processors online, acquired a small company called AppJet whose EtherPad service fits into that agenda.
AppJet announced the Google acquisition Friday. "The EtherPad team will continue its work on real-time collaboration by joining the Google Wave team," the site said.
AppJet offered free and premium versions of its service, which could import Microsoft Word documents, Web pages, PDFs, and plain text files, and let groups of people edit them collectively on what it called pad. A "time-slider" feature let people look back at earlier incarnations of a pad.
Google Wave has similarities. It's a sort of hybrid between instant messaging, wikis, and e-mail. Google Chief Executive, in particular given its intrinsically networked nature and its real-time view of what collaborating people are up to.
That real-time collaboration is a thorny problem. It can be difficult to permit multiple people permission to edit the same document at the same time while ensuring one person's changes don't interfere with another's work. And showing simultaneous work complicates a service's user interface, too.
Google Docs--the online word processor, spreadsheet, and presentation services--also offers some simultaneous editing abilities. AppJet dings it in its EtherPad FAQ.
"With Google Docs it takes about 5 to 15 seconds for a change to make its way from your keyboard to other people's screens," the site said. "Imagine if whiteboards or telephones had this kind of delay!"
Google Wave and Google Docs are perhaps the closest rivals to AppJet, but in the big picture, the rivalry is between cloud computing and the way most people use productivity software today, on their PCs. Notably, though, Microsoft is working on an online version of its dominant Office suite.
Current EtherPad users should brace themselves for the end of the service: "If you are a user of the Free Edition or Professional Edition, you can continue to use and edit your existing pads until March 31, 2010. No new free public pads may be created. Your pads will no longer be accessible after March 31, 2010, at which time your pads and any associated personally identifiable information will be deleted," AppJet said.
"Super-lame that Etherpad is shutting down. We used it all the time for jQuery planning," Resig said in a tweet on Friday.
