Column: YouTube comments will be tied to Google plus

Google is about to require a Google Plus account to comment on YouTube videos, which could give both properties a boost.

Google is the undisputed king of Internet search. Last month, its share of the search market was 67%.

It even makes the most popular browser, Chrome, with 52% of the market.

Gmail is also the world's largest email provider, having beat out Microsoft's Hotmail in October of last year.

But with its several forays into social networking, Google didn't have so much luck. Buzz was dead on arrival. Orkut was a noble effort but it mainly lives on in Brazil. Google Plus was well received, but two years after its launch, it's still basically a ghost town.
