I recently came across this term while examining a set of properties in a JSON feed relating to a startup company:
... "deadpooled_year": null, "deadpooled_month": null, "deadpooled_day": null, "deadpooled_url": null, ...
I searched for the word, and find several non-authoritative sources (e.g., The Urban Dictionary), but nothing definitive. I gather it means something like "defunct" or "obsoleted" — handed over to the pool of dead companies which have been surpassed and made irrelevant by other, more successful companies. I also infer that it is a fairly well known term used in the startup lexicon. Yet this is the first time I've encountered it.
Can anyone shed some light on the term "deadpool" or "deadpooled"? A citation from a serious publication that uses the term in a way that makes the meaning obvious and unmistakeable? Please, no speculation. I have already speculated enough about this.
