Somehow gmail manages to auto suggest and complete email addresses for me. Sounds a lot like they tracking who I correspond with.

Yes. 2s/aim/initially aim/

I rarely use Javascript (certainly not for email) so I wouldn't know about all the latest Gmail "features". :)

What I was hinting at was a sort of evolutionary pressure on Google... to start using personally identifiable information. That pressure being Facebook as a perceived competitor.
