I am a big time user of Google Alerts, I just don't use them via email - but rather via RSS. Some users are reporting in both a DigitalPoint Forums thread and WebmasterWorld thread that Google Alerts seemed to have just gone a bit out of hand.

I've also been getting some peculiar Alerts again - and in some cases they are things that should have been sent a while back. I'm not seeing any impact on the SERPs from these new pages, however.
Yea, my Alerts have gone nutso over the past few days to a week.

The last 5 days I have been getting about about 5 or 6 emails a day, when I just used to get the odd one here and there.
Each email also has about 4 or 5 links
Like I said, I don't get these alerts via email - so I don't really notice the issue. Do you?
