Years ago I found a site that did a really good job of ranting about
Microsoft. It contained a series of articles called
"Understanding Microsoft" by Tom Nadeau. Sadly, this site went off line
at some point in 2010.
However, at the time of writing (July 2012) it seems to be
back again.
I haven't had time to put together a proper rant myself, so you will
have to make do with
The Halloween Documents for now.
and
a rant by Eric Raymond.
