I think we can all remember the 'active' email contacts.
It would be more interesting to get a reminder of the 'dead' contacts in the list.
If you/they did not write in 2+ years chances are the address is dead anyway and can be removed.
Or maybe Google should have an 'auto check' system where it just pings an email address to see if it is still active.
Eric Schmidt started the trend of taking what seemed like "good" ideas and making them look creepy. Disappointing to see even without his general influence the trend seems to still continue. I guess it has its uses for some people, but for the average email user it just looks and sounds creepy and useless as if the entire purpose is to show the user the flexibility and power that Google can leverage based off there use of their systems.
