Wondering if this is an April Fool’s Day joke or not? OnStar, has according to Gearlive plans to launch Twitter integration into their handsfree communications offering in cars. According to Gearlive, “While in your vehicle, you can use OnStar to submit and retrieve tweets (messages) via your Twitter account. Using OnStar’s Voice-Activated Hands-Free Calling system, and having your voice converted into text, you can provide updates which would appear in the “What are you doing?” section of your Twitter homepage. It is also possible to listen to a tweet that was sent to you by someone else after it has been converted into voice. You can send and receive tweets without having to type or read anything.”

Has anyone already seen an April Fool’s Day joke by Google? They have quite a reputation for this, but the Wiki has not yet been updated with this year’s joke. Maybe they have decided not to do anything this year?

UPDATE: The Pirate Bay selling out to Warner, The Guardian swapping print for Twitter. Here’s a nice roundup of this year’s April Fools.
