I thought of that, but decided against it. Discussion posts get buried more quickly and thus are likely to get less exposure. Furthermore, the purpose of posting this is to spur action, not talk -- discussion is more for when you want to talk about something.

There is a discussion post already for the general concept of making promotional videos of cryonics here.

Other ways of promoting cryonics and related concepts -- cartoons, billboards, t-shirts, blogs, hiring ad companies, and so forth -- can certainly be discussed in further discussion posts if anyone is interested. The caveat is that, beyond a certain point, more time discussing equates to less time doing.
