Google Calendar?

Gosh, do the folks at Google ever sleep? This via Threadwatch:

"The subdomain calendar.google.com is active. Does this mean we will be seeing another Google product this year?"

In the last few months, Google has produced:

• Google Reader: "makes it easier to keep up with your ever-expanding reading list of content from across the web."
• Google Analytics: "tells you everything you want to know about how your visitors found you and how they interact with your site......Google Analytics delivers all the features you'd expect from a high-end web analytics offering, and provides timesaving AdWords integration features." Unfortunately, this service has been closed down temporarily.
• Google Talk: It's an instant messaging service plus that enables "you to call or send instant messages to your friends for free–anytime, anywhere in the world."
• Google Base: Google Base is a free online database that allows anyone to post anything (as long as it falls under the Google Base Program Policies) they want.
