They say that there's very little difference between love and hate. A good example of this is the Linux Hater's Blog. It's written by someone who obviously has a lot of experience with Linux and Open Source, and I get the feeling that the hate comes of frustration and pain. Certainly, I've seen plenty of similarly themed articles coming out of Planet Debian at one time or another.
One of the best articles I've found yet is One bug report to rule them all, a humourous but altogether painfully accurate rendition of far too many bug reports I've seen and dealt with of the years.
