Reviewers can often be frightened by walls of text, especially on an article whose subject might not appear at first glance to be that interesting.  Give it a while and then renominate it, but next time, include in your "reason why this is FA" a proper description, something to hook people.  For instance, look at the reason I gave in this FAC nomination.  And give me a shout, I'll review it for you.  of Doom
