Spotted tonight by John Milan, Google has a promotion for its online shopping product Google Checkout on its homepage - probably the most traffiked web page in the world.
Also there's some interesting speculation over on the Cost Per News site that Google Checkout is set to ramp up:
"IÄôve heard rumblings from my sources within the company and from a few of the merchants involved in the Checkout program that something major is on the wayÄ¶ soon."
See also Donna Bogatin and SearchEngineLand, both of whom cite some worries over Google's management of Checkout. On the latter link, Danny Sullivan says that "Google's not thinking clearly about the best way to balance promoting its own products and the trust of users."
More on this story as it develops, as I'm sure it will...
