Comment: Nomination is a misapplication of #INDISCRIMINATE.  That section of policy does ''not'' deal with whether or not information is "important".

If the nominator wishes to argue those points, then he should refer instead to with  or Wikipedia:Notability and attempt to claim that the article is either unreferenced or not notable
