Google going integration.

I went out of my study table limits and covered GooTube integration with Orkut. (here) . Things which I have been saying since long time are getting in shape, and this proves that there are intelligent people working for Google. Recently they have been putting few tips to for their service users to work in tandem with their other services.
Heres one example...

The above mentioned example was already present, and you can see it working on this blog also. But having a service and having a known service are two different things and they are making people aware of what Google have up their sleeves to offer. And its good.
There can be few people who feel that this is unwanted, but I think that as a big company they should certainly promote users to use their service, because better integration will always save time.
Heave you noticed any other example of any such integration then you can certainly send a tip off.
