I understand that new articles get close scrutiny but just how do deletable articles that have been around for a while come to the attention to those who regularly nominate articles for deletion? (especially if the article is otherwise well written)
I ask this because recently I came across a fairly well written article about a computer term that had a prod tag on it for being an unsourced neologism. It probably was since all the google hits for it pointed to mirrors of its WP article but I still decided to replace the prod with a sources tag to give the original author a chance to add a source. However, I started to wonder why the person who first prodded it suspected it was a neologism as it couldn't have been the first term he ran across on wikipedia that he never heard about. Does he prod them all?
The same could be asked about notability. Just what makes one suspect that a particular person/band/school/company/webcomic etc. is not notable? Please note that I am not saying that such articles should be kept but there has to be something in an otherwise well written article to cause someone to investigate the article's eligibility to be in wikipedia besides "I've never heard if him/it"
