Comment: Hmmm, I am not sure why I withdrawn the nom, the sources added (see https://en.wikipedia.org/w/index.php?title=Deadline24&oldid=571339472, removed since) were not great. That said, while the article is effectively unreferenced now, I see some coverage in Polish media. http://katowice.wyborcza.pl/katowice/1,35063,19895853,deadline24-znamy-zwyciezcow-maratonu-programistycznego.html is a regional edition in a mainstream and very respectable Polish daily; think like a regional insert to New York Times or USA Today. Another good coverage was for 2013 in https://www.chip.pl/2013/04/kliknij-tutaj-zwyciezca-deadline24/ :pl:Chip (polski magazyn), that's Polish equivalent of PC World or such. Leaning keep (other sources I see are more like press release, or I can't open them). Still, this is not terrible, as far as coverage goes for this kind of events, and I think it may pass
