Thank you.
I was bored and too lazy to do work so I made a PHP script that counts the number of occurences of "gloomy", "end-of-the-world-ish" words in Google News:
World Gloominess as gathered by Google News.
Another thing you can do is feed it your own URL, for example: http://zaim.frens.net/gloom/?url=http://www.petalingstreet.org will count the gloominess of PPS.
Also, check out the gloomy words list. Tell me if you like to add other words to the list.
<Update>This script is released in the publid domain. Go here for the source code.</Update>
