I used to use SpyOnIt.com

I used to use SpyOnIt.com as my favorite notification mechanism. But no more. SpyOnIt looks very ill, ill unto death, sad to say. It was a good service, but then again, I never was clear on where their money came from. Now I’m using NotifyList.com — sign up in the box at the bottom of the left panel if you want to be notified when the Rambles weblog is updated. Of course, I’m not sure how NotifyList makes their money, but why worry? Everything’s going to be fine, right?
Just use http://www.changedetect.com/ or http://www.wisdomchange.com/. They still work.
