The proper place to complain about these things is in the support/feedback forum (a.k.a., Get Satisfaction). I bet that this has been brought up quite a few times already, so add your voice to the protest...

After all the complaints I have seen in the forums, I was rather surprised to find that this has barely been covered in GS.
 
What is that they say about "assuming"?

PLease, drop by thisGS topic to express your opinion!!!

Hey guys, thanks for bumping this back up. This might be something we consider as an opt-in feature. We want to make sure we don't bombard people with emails left and right along with our standard digest and notification emails.
 
We'll monitor this thread to see who else chimes in and has interest in seeing this implemented.
