It honestly pains me greatly to know so many different ways I could "improve" this article, all of which involve actually making it needlessly longer and more complicated

It is ironic that you chose to make this reply to a comment that essentially objected to a needless (and misleading) complication in the title. If you left it at "How to Donate $100 to SIAI for Free" and didn't introduce a complexity ('Applied Optimal Philanthropy') that goes against the content then your post would have earned a whole lot more karma and a more positive response.

As for "all of which involve", the other suggestion you were given here was to post things like this in the discussion section - another thing which has absolutely nothing to do with 'making it needlessly longer'.

simply to appease the highly-perverse expectations here that knowledge which is simple to attain is not valuable.

No, this is nothing to do with 'highly-perverse expectations'. If (and this is something that I doubt strongly) people here are particularly prone to believing that knowledge that is simple to attain is not valuable then it is still irrelevant to the criticism that you are so bitter about receiving.

Once again, I like being provided with tips for making money. I don't like pretentious sulking.
