Yesterday Google announced about yet one more service to the community ! Its Google Pedia ! It will definitely compete with wikipedia and about.com. I am sure Google will win the race too in short time.
Google offered sharing of ad revenue to authors of their pages. That may be an advantage over wiki. I am sure lots of people will start "blogging" there !
Initial announcement said, web is not having tradition to write Author's name below their articles unlike print media. Still local news paper like Gujarat Samachar still dont write it in print media too !
