The community base has changed since the last awards, there have been a large number of active newbies joining and a good number of oldies leaving, at this moment in time I don't think many people know the majority of newbies/oldies well enough to feel comfortable voting outside of lucky dipping names from the provided list. So the votes are likely to be fewer in number and take longer to come back as people can't just rattle off active users in their head.
Even though I know the usernames of the currently active members, I haven't seen enough of their textual personalities to do more than lucky dip them when it comes to categories. Or express huge amounts of favouritism and only vote for people I know/communicate with/find tolerable.
Give the people a chance to get to know each other
