In 1977, the movie "Saturday Night Fever" was link bait for Robert Stigwood to sell the sound track album. That same year, George Lucas released "Star Wars," and one of his business goals from the start was to "Build a Real Company," which he did by exploiting merchandising tie-ins.

"Link baiting" to sell a book is a kind of tie-in, just like sound track albums and toys. If what you say is true, then this post is an example of the pop culture it depicts. That would be pleasingly self-referential.

Alas, it isn't true. I wrote a different post yesterday, one about the I Combinator in CoffeeScript. That one was a deliberate tie-in to my book. Some of the feedback I got from /r/javascript was that the idioms were unfamiliar to the JavaScript culture, which provoked this post.

So yes, I do write posts with the thought of promoting my book, but no, this wasn't one of them. But yes, as long as I'm writing a post I include a link to my book. Why not? I read a lot of posts with advertisements on them. Why advertise someone else's dream?
