根据我的了解：43things的创建者只是想找一个小于50的质数：而且43folders和43things没有任何关系。
In fact, the coincidences continue because 43 Things was also inspired to some degree by Dave Allen – but the idea for 43 only entered on a subliminal level. We considered 23 and 37 as well as well as 43 – we just wanted a prime number less than 50, and settled on 43 as the right number of things to try and do.
We registered the url and set to work building out our company with no idea of any 43 meme. Anyway, if 43 ends up meaning smart, fun and useful – like 411 means info – maybe it will all work out for the best.

好比人可以用十二生肖×十二星座进行分类：43things * 23people也都是将事物进行分类/分群的一种机制，而且使用2个质数，其分布会更加均匀一些。遇到卢亮这样想像力丰富的朋友：任何数字都会有其有趣的一面，但和“历史上的今天”一样，每天都有大伟人诞生，都有伟人逝世。每个数字后面都有精彩的故事……
