I've in been in rant mode the last couple of days, not just writing them, but have enjoyed reading them too.

Here's a good rant by Mark Baartse - 'the fault of defaults' is all about how crap user exepriences (that's the technical term) in software are often on by default and his exhasperation at these "substandard user experiences" (that's the client-facing term) being left on in 80-90% of the deployments he's seen, even though these defaults can be easily toggled off.
