Note: I am not asking why is there a minimum limit.
Previously closed as dup, but neither of the "duplicates" answer this question!!!
The suggested dups were:
Both of which ask why the limit is there. I know why it's there. I'm happy it's there.
This question is asking why it is 15 (and not 14, or 16, etc)?
Was any thought or research put into the choice, or was it just based on feel?
Some examples of reasons for choosing 15:
- Was some statistical analysis done on comment sizes?
- Was the limit borrowed from an external academic or commercial source?
- Was it decided on by committee?
- Is it because it's the largest length that can be represented by a single hex digit?
Also note: I don't think it's a bad limit or needs changing. I am just curious to know why 15 specifically was chosen.
The reason I'm asking is if the reason has firm basis it, that basis could be valuable info for someone researching lower thresholds of meaningful communication.
