Turns out this is not news at all. This service has been running on Google China since 2007, apparently :)

http://wenda.google.com.hk/wenda/

Also known as Otvety in Russia http://otvety.google.ru/otvety/ (June 2007 http://blogoscoped.com/archive/2007-06-29-n26.html).

Also, if you look at http://www.google.com/images/nav_logo26.png (all navigation logos for google.com) there's a green question mark icon that could be used for an upcoming US version of this Q&A service.

Clearly this is a replication of stackoveflow concept: http://stackoverflow.com/

Of course Wenda and Otvety have been well-covered in Blogoscoped.

But for years Google has conspicuously avoided launching an English-language competitor to Yahoo Answers, presumably because Google has "something better" cooking.

And again, I think the development and promotion of baraza by Google in Africa (despite its usability throughout the English-speaking world) reinforces that Google is still cooking up "something better" for more affluent English-speaking markets.

Remember Google Guru??

I am going to develop a program to log-on this service everyday, pick some best answers, answers some questions with a content-sensitive knowledge database. Then in a few week, this program will become the king.

Using similar scheme, the program running on various accounts may get questions from yahoo answers, and get respective answers to post to google QA as well.

A spam bot which basically replicate yahoo answers to google QA. It there such spam out there already?

Bringing this service to Africa is a great idea. Making locally relevant information in a location where there is none on the internet makes this internet relevant.
Really, people out in the deep parts of Africa could care less about American celebrities or the top Yahoo news stories. They could use local information.
Unfortunately, as this service is open to everyone in the world, Africans will soon get flooded with garbage posts like you see on Yahoo news. (Seriously, you ever want to feel bad about America, just read some posts on Yahoo news comments.)
