If you had to pick exactly 20 articles from LessWrong to provide the greatest added value for a reader, which 20 articles would you select?

In other words, I am asking you to pick "Sequences: Micro Edition" for new readers, or old readers who feel intimidated by the size and structure of Sequences. No sequences and subsequences, just 20 selected articles that should be read in the given order.

It is important to consider that some information is distributed in many articles, and some articles use information explained in previous articles. Your selection should make sense for people who have read nothing else on LW, and cannot click on hyperlinks for explanation (as if they are reading the articles on a paper, without comments). Do the introductory articles provide enough value even if you won't put the whole sequence to the selected 20? Is it better to pick examples from more topics, or focus on one?

Yes, I am hoping that reading those 20 articles would encourage the reader to read more, perhaps even the whole Sequences. But the 20 articles should provide enough value when taken alone; they should be a "food", not just an "appetizer".

It is OK to pick also those LW articles that are not part of the traditional Sequences. It is OK to suggest less than 20 articles. (Suggesting more than 20 is not OK, because the goal is to select a small number of articles that provide value without reading anything more.)
