For some time, fairly long ago, most StayOnTop posts came with a Mood Meter at the top. This was a kind of half-serious, half-satirical running gag. The Mood Meter pretended to warn the reader about what mood I’d been in while writing the post.
I’ve now scrapped the original “Mood Meter Explanation Page” that was here, legal disclaimer and all. But occasionally you can still run into one of my old posts that still shows a Mood Meter, linking to this explanation page. This is probably how you got here now.
Sometimes people clicked the Mood Meter because they were looking for an actual Mood Meter, a way to gauge and monitor their own mood.
If that’s the reason why you got here, I want to refer you to my Mood Monitoring post.
That one is about the question whether it’s wise to try monitoring your mood every day, and it also discusses an actual kind of Mood Meter service (Mood 27/4) that works with daily SMS mood reporting and a webpage that graphically shows your own mood changes.
So maybe you should take a look there.
