> Because there's very little effort required to flag articles for deletion, and the burden to keep is often on the contributors doing research on a 7-day timeframe if there are even just one or two editors supporting deletion, most times the contributors eventually give up running the research treadmill and the content gets deleted anyway. Pretty much sums up the problem with every community-run moderated site. It directly leads to the downfall because contributors get discouraged and leave, and eventually all that's left is people with the same view as the heavy-handed moderators. Having hours of work wiped out from editors/moderators who've spent less than a minute on it sucks. Stackoverflow is another notable example of this.
