Just heard a bit of news directly from JotSpot that they have officially closed a deal to be acquired by Google. A busy fall for Google with the recent YouTube acquisition and now the acquisition of JotSpot. As with the Writely acquisition earlier this year, new account creation has been temporarily suspended while they move to the Google architecture, but you can sign up to be notified when registration reopens. JotSpot has posted a Frequently Asked Questions page, and co-founder Joe Kraus writes more about the deal on the Google Blog. This certainly adds one more element to Google's collaborative office strategy.
