The angry programmer?

My wife thinks I should start another blog named "Ulriks programming nightmares". Or maybe just add another topic of this blog where I mention examples of programmed systems that aren't good. Or to be more precise, where the programmer was too lazy to do a good job, which really gets me going. Unfortunately I get upset when I see it among the students which is a bit harsh, they are here to learn after all.
The examples I have seen so far is everything from the logic of the elevators at the university to how the booking system of SJ places people at a train. Seriously, if there are 3 reserved seats in a wagon, why must two of them be next to each other?
Enough ranting, but is this a good idea to expand the topic of the blog with? Coming to think of it, there must already be sites like that out there. If not there should be, it is always more educational to learn from bad examples than good.
