Google continues to run the “feature race” in the social network battle with the announcement of four new Google+ features: What’s Hot, Ripples, Creative Kit, and Google Apps integration.

What’s Hot is pretty self-explanatory. It’s a place where you can see interesting trends on Google+. The following video explains it anyway:

Ripples is a tool designed to help you visualize the way your posts flow throughout Google+. You can simply view a public post and select “view Ripples”. The video below illustrates who this works:

The Creative Kit a set of photo editing tools for Google+:

There are even some special Halloween effects available for a limited time. “Through the end of October, simply add some spook to your photos, and share them publicly on Google+ with the hashtag #gplushalloween,” says Google SVP of Engineering Vic Gundotra. “We’ll assemble a surprise panel of celebrities, and next Thursday, Nov 3, they’ll announce their favorites. In the meantime, you can see early submissions from community members below. After all: we take our fun very seriously.”

Finally, Google+ integration is available for Google Apps customers. “Starting now you can manually turn on Google+ for your organization,” says product manager Ronald Ho. “Once Google+ is turned on, your users will just need to sign up at google.com/+ to get started. For customers who use Google Apps for Business or the free version of Google Apps and who have chosen to automatically enable new services, Google+ will automatically become available to all of your users over the next several days.”

Users can share publicly, with Circles, or within the entire organization.

Google says it is building a migration tool for those who are already using Google+, but want to switch from a personal account to a professional one.

The features aren’t completely rolled out yet.
