Ok, I'm going to approach this a little delicately, because the last thing I want to do is push enthusiastic new contributors away. Indeed, if this silly game I came up with actually attracts new people to the site then that's something I'd be quite proud of. So welcome.
It is true, however, that the current margin in this thread is three votes, and there have been three votes by new members from the Netherlands, who are no doubt very proud of their home country zoo (I certainly would be, as it's easily one of the five best I've ever seen). So what I want to do is just make sure everybody understands exactly how this game is supposed to work.
The poll is *not* about whether you like Burgers more than Wroclaw. If it was, I would vote for Burgers, though I have in fact voted for Wroclaw. That's because the scope of the question is strictly about which zoo is better for reptiles, amphibians, fish and invertebrates. Everything else has to be disregarded. This has been by far the most contentious and enthusiastically engaged in match of the entire project, and I really want to make sure that the purpose of the game is taken into account, so everybody can be confident in the result.
I will not be disregarding any votes: everybody is welcome to contribute, from the newest of newbies to the ultra-obsessives with hundreds of zoos and ten thousand posts to their name. And I have neither the right nor the ability to judge people's reasons for their vote. At the same time, I hope everybody keeps the parameters of the game in mind when they vote, or indeed when they consider whether to change their vote.
The poll remains open for another 30 or so hours. Plenty of time for everybody to keep trying to sway a pivotal couple of votes to their side. May the best zoo for ectothermic animals win.
