If the provider charges a fee for the session, both providers and customers will need to use Google Wallet for the payment, according to the Helpouts site.
Helpouts has a strong social component for a reason: Social networking is an area of Google's business that the company is continually seeking to scale out to better compete against rivals such as Facebook and Twitter. While Facebook and Twitter have more than 1 billion and 200 million active users, respectively, Google+ has about 190 million, the company reported in May.
Google already provides videos covering practically every topic through its YouTube video-sharing site, some of which are instructional in nature. But Helpouts looks to be a step up in both the level of interaction and the qualification of the experts, given its current invitation-only sign-up process.
