fanfic rants
The lawsuit between JKR and uberfan Steve Vander Ark has caused a huge rift in fandom. The pro-SVA side is often categorized as DH haters or Over-zealous shippers. However, I think much of the Pro-SVA is made of fan fiction writers. These are the people most likely to use the Lexicon, the biggest fans. These writers also understand the desire to take some of HP and make it your own. There's really no way to measure but I'm betting that many of the pro-SVA come from this group.
