still fundamentally need to sell

[Sarcasm] Unlike companies, which are apparently altruistic organizations that exist for the betterment of humanity! It's all those fools who keep yelling "companies exist to make money" who are wrong. Yeah, that must be it. Tech companies charge because they're good, whilst various writers give away some, much, most, or all of their work because they're evil! Sharing is DEATH, kids!

Sorry, I went off a bit there because I'm frustrated at how committed you are to your bad ideas. Also textbooks also have to be sold, at least here in the US where many are (were?) tailored to the anti-education pro-horsecrap preferences of Texas.

Side thing: I'm becoming increasingly convinced that FaceDeer as an account/persona/whatever exists specifically to be mildly irritating. Is that true? Would you admit it if it were?
