This is what I do.
Anytime I'm in front of a computer I have a browser up with spy. More than one if I have the space. It helps when you actually have to post you can see your post went through when it is still loading on the posting page.
And when I have to do something away from the computer I use my phone or iPad with a browser open and spy up.
I'd love to have a good notification devices, but nothing seems to be reliable when 40 seconds is make or break.
