Angster (n). angsters are people who as part of the blogworld or whatever world they might think they exist in, proceed to express angst. Ongoing, and indeterminate of cause, though any given cause is the cause of the moment, angsters spew their worries and feelings about it for their audience, their people, or frequently just themselves. angsterize, angsterate, angstiferous.
I believe in angsters, and I believe they have effects on other people that are almost entirely negative.
