Google Plus gets user-friendly tweaks

The most visible change is a new navigation ribbon on the left side of the Google Plus page with icons for the most used features, such as games, photos and your personal profile. Hover over an icon to do specific tasks, such as add photos from your phone or an online album.

You can reorder the features in the ribbon and hide the ones you don't use often.

The changes, announced , are designed to help Google Plus adapt more easily to growth -- and to make room for new features in the future.

In a blog post Google calls the ribbon "an obvious (and clutter-free) space for The Next Big Feature, and The Feature After That."

Google is worried that Facebook has been carving out a competitive advantage by stockpiling valuable information about people's social circles and interests. The data has given Facebook the means to target ads precisely and deliver content tied to a user's hobbies and tastes.

Google said Google Plus has attracted more than 170 million users since its debut nine months ago. That lags Facebook's 845 million user count, but it's far greater than Facebook's tally at that stage in its history.

Among the changes: A navigation ribbon for customizing a page; an easier way to build a community around content you post; a "Hangouts" icon to make it easier to find and join group video chats; and an "Explore" option which points to content that's most popular and talked about.

Google Plus users will see the latest changes this week. Some features that were available before will become more prominent with the redesign.
