Don't know why, but that question has been on my mind all day. I'm not even sure why it bothers me. It just.... does.
I've never been very involved with the table top aspects of Warhammer 40k simply because of the prohibitively high entry cost. The Dawn of War series of video games has gotten me hooked to the lore though; I'm thinking about setting up a Tau table top army when life settles down a bit and I get my finances in order, which won't be until well within the next school year.
Probably something that relies heavily on human auxiliaries and Tau armored assets such as battlesuits and (especially) gunships.
Now you know. You can thank me later.
