This question already has an answer here:
- Is programming history on topic? 5 answers
Is curiosity allowed on the various stackexchange sites or does every single question need to be a question about a precise problem to solve?
For example, are the two following questions valid questions:
"When did Huffman discover his minimum-redundancy-code?"
(not that the answer to that one is hard to find, but I'd like to know if that would make for a valid question on a SE site)
Or the following (asked by me):
I mean, to me they're interesting question in themselves but a mod pointed to me that:
"(the question) may be interesting but it's not what this site is about"
I think a case could be made that knowing the "history" of algorithm, data structure and techniques is interesting in any case: it helps understanding how things evolved and may give insight as to why some other things were made this or that way.
But even without taking that into account: are interesting question just made out of curiosity not allowed on SE?
(just to be clear: I made the above question because I'm currently working on implementing said tokens and I wanted to read material on the subject and figured out starting from the oldest material available would provide good insight on the topic: that old Usenet post from 2003 I found was certainly a good read, for example)
