<< When's the last time you got an email from a stranger asking, "Are you sure you meant to send this to me?" and promptly realized that you didn't?...

If you normally email Bob Smith together with Tim and Angela, but this time you added Bob Jones instead, we'll warn you that it might be a mistake. Note that this only works if you're emailing more than two people at once... >>

Ahaaaaa (to quote Alan Partridge) I saw this on Marie Claire first – via fastflip – progress, you bet

forgotten attachment detector doesnt work for me either...

This is scary. Why? It means they are building heuristics on your behavior. They know you mail Person A and Person B alot. So their suggestions are predictive analytics based on what you have been doing all along. How soon before they tell me I should email Bob too? I.e. Not the wrong bob but what about bob?

Ever turn Ads On in GAPE? Watch how it reads your threads. If you have a mail about a business trip to Pittsburgh, you get ads. If you have a mail about new product line to compete with Ford, you get Ford ads.

When I turn them off, no ads but they are still reading my mails.

They already have this. They launched this back in April...it was called "Suggest more recipients" until they just renamed it to "Don't forget Bob".

See the end of this post where they discuss renaming it: gmailblog.blogspot.com/2009/10 ...

<< While we were at it, we also changed the name of "Suggest more recipients" to "Don't forget Bob" — the two related Labs features just kind of went together better this way. >>
