>Lastly, IANAL, but I doubt promoting one of your products on one of your products is in any way illegal.
Wasn't that the whole issue with the Microsoft anti-trust suit - that Microsoft bundled ("promoted") IE with its other product (Windows)?

Microsoft used its desktop OS monopoly to ensure that IE was far and away the most dominant browser on the internet. It's a great example of how these sorts of otherwise-legal tactics, when taken to the extreme, can lead to situations that are bad for consumers -- which is why the anti-trust laws exist.
Also, my point still stands - Google has been promoting other products on their homepage for a long time without getting sued. I don't understand how Plus would be different from, say, Reader.
