Another neologism:

shadenblog: to gain gleeful pleasure from reading someone else's blog and feeling smug that your life doesn't suck so much as that of the person whose blog it is, or that you are not as big an idiot as the author.

[By the way, I have one particular blog in mind that I read, and it doesn't belong to anyone I know or have ever met, so don't think this is about you. Unless you happen to be... oh, but that would be cruel]
