Google will be soon launching a new service, Google Sites, based on their acquisition of JotSpot. This will make Google's online collaboration offering for businesses even stronger.
The word on the street for some time has been that Google is the new Microsoft. If Google doesn't already compete with you today, they sure will tomorrow. Talking about online collaboration tools, should 37signals be worried? At Orbeon we are using Basecamp; we have found it to be a great tool, but have been disappointed to the lake of improvements to Basecamp during the last couple of years. Come on guys, it is time for a major update to Basecamp, or others (yes, Google) will soon be providing a more complete and more competitive offering.
