EDIT: I was being presumptuous about presumption, so, presumptive comment removed. Presume.
I was not trying to be presumptuous. I really believed you were wrong. GChat just sounds wrong to me. However, something sounding wrong to me has never stopped it from being true.
Apparently Google endorses Google Talk and resists the GTalk name. I guess it's easier to be found when your page title is Google Chat even when the service is called Google Talk (did you notice Google Chat is not anywhere but the page title?)
Also, I wasn't presumptuous, it was just an innocent remark.
