Last week Google unveiled its latest foray into social networking, Google +, in a limited invitation-only release. For a platform that is still in its infancy, it’s already causing quite a commotion, garnering a reported 10 million users, with some heralding it as a future Facebook disrupter. But between Twitter, Facebook, Tumblr, and Foursquare, social network-weary users are right to wonder—do we really need another platform to keep up with?

A few promising features make this new kid on the block worth taking a chance on:

Circles – The cornerstone of Google +’s platform allows users to be selectively social. Users can place their connections in “circles” or separate groups to share certain information with. Facebook users that shy away from sharing things with all 600+ people on their friend list—encompassing everyone from a weird uncle to a boss—can rejoice. Google + allows users to easily categorize the people in their lives by dragging and dropping them into different “circles”—each defined by a unique type of interaction.  This allows users to have something beyond just a social network online; it allows them to have an extension of their real-world relationships in the online space. Circles help users maintain the divisions that organically form in their lives and create a closer bond between online and offline interaction.

Circles can also function like Twitter, by allowing users to follow certain celebrities or personalities and interact with them. This functionality combined with the many features of Google + (especially Hangouts) allow more personal connections with celebrities and persons of note.  Bloggers like Kevin Rose (founder of Digg) are already migrating to Google + as it allows them greater and more in-depth real-time interaction with followers. Circles could prove to be a powerful tool in closing the gap between luminaries and their followers.

Hangouts – Hangouts are a feature that makes “hanging out” online a bit more like organic, offline gatherings. Hangouts allow video chats with up to 10 people, and a user can start a hang out with certain (or all) circles if they are looking for a conversation; friends can join a “hangout” or drop in on a conversation to join the video chat.  For Facebook users that instinctively revert to “invisible” on chat to avoid unwanted messages from distant connections, Hangouts are an easy way to make yourself “visible” to certain circles, similar to when you choose to hangout with certain groups of friends.

Teachers, politicians, and celebrities alike are also beginning to recognize the potential of this feature.  University professors envision using hangouts as a virtual office hour, where students could join in a collaborative questioning session. Presidential candidate Newt Gingrich hosted his first hangout on July 8, where users could join and ask the former House Speaker questions about his policies. The implications of this feature are enormous. While politicians may have been able to field questions from voters via Twitter in the past, the impact of a face-to-face conversation is much more powerful.

Sparks – Users can search for and select categories of interests, like “Sports” or “Street Art” and are given a stream of posts and news online related to that topic. While this may seem like Google Reader or any type of RSS feed, the beauty of Sparks lies in its integration and simplicity. Within Google + users can view stories about certain Sparks and share with certain circles with the click of a button. Although Facebook has a similar share functionality with Facebook Connect, this requires users to leave the Facebook platform to seek out news. By combining the search, news, and sharing platform all into one, Google + has made it effortless to discover and disseminate the latest internet treasure. This feature could prove valuable for bloggers, who can curate content on their own profile and share with followers (in a format longer than Twitter). The integration of content discovery and sharing into one platform could help turn Google + into a social hub for users, where they can find content, chat, and connections in one place.

So is Google + the harbinger of Facebook’s demise? Probably not—at least not yet. With over 750 million users, and deeply rooted social networks, it is likely that people will not be forsaking their profiles in droves. However, Google + shows exciting promise, making it worth exploring. It allows us to dissect vast social networks into manageable pieces. It allows us to move away from being simply a third-party commentator on other people’s activity. It allows us to bridge the conversations we have online and offline. Google + has potential to foster moments of connection more intimate than a simple “like” or tweet.
