They all really were fantastic articles and I'm flattered that I'm still in the hunt, thanks to everyone that voted. Also, amongst the articles that ended up with relatively few votes were several that I seriously considered voting for myself so I hope no one feels disheartened! I think it was a tough decision for everyone and any of them would have been worthy winners.
I think I'll refrain from voting in the decider. Good luck FB!
EDIT: FB voted for me this time round! I'll return the favour (only fair, especially considering he got my vote last time!) Thanks!
