Google doesn't offer an API for Google+ thus making it impossible for you to cross-publish status updates to Twitter or Facebook.
If you started your online social life on Orkut but later migrated to Facebook, here's a simple import utility that will help you become friends with all your old Orkut buddies who may have shifted to Facebook as well.
The orkut Mobile App is a free application for your Java enabled mobile phone . This Orkut App will help you send scraps, upload photos and even share albums with your friends via SMS. Coming soon.
If most of your friends and family members have a presence on Orkut, you'll be happy to know that you can now add your orkut friends' birthdays to your Google calendar.
The iPhone version of Orkut is more feature-rich than the older mobile version in the sense that you now read friend updates, delete scraps and even view photo albums right from the iPhone.
You can now add OpenSocial applications to your Orkut profile just like way you add apps in Facebook.
Google launched a mobile version of Orkut at m.orkut.com - the new mobile site lets you read Orkut scraps, receive updates from existing friends plus you can approve or decline new friend requests.
A Google Account gives you access to all Google goodies including AdSense, Analytics, Blogger, iGoogle, Gmail, Google Groups, Picasa, Web History, Google AdWords, Google Checkout and more. But you can run into problems if you have opened more than one account.
Orkut has a little spying feature called “profile visits” that automatically shows a list of people who have recently viewed your profile page on Orkut.
