what about Google Answers?

Today I found this google service on th internet:
http://answers.google.com/answers/

After some research I noticed that this service is not new (launched april 2005)

why is this service not promoted on other Google pages?
for example here: http://www.google.com/intl/en/options/index.html

I this service a way to earn money?

I think this is because they have so many services that they really need a big portal site just to promote them :)

The google answers site, is actually a copy cat from another simillar service in the past (which I can't remember the name)

Anyway it looks like a place where proffesionals can earn some easy money.

I checked some time before the yahoo answers service, but that was a free service (maybe good for SEO)
