Fair warning
The “popularity contest” plugin for Wordpress is the buggiest piece of garbage I’ve ever seen. I installed it on this blog and it worked, but then suddenly it started doing all this weird stuff to my admin system. I tried installing it on my other blog and it didn’t work at all. Support is also garbage; at least four people have listed the same problems as I have and none of them have gotten any responses.
Turns out it’s a problem with mysql; the plugin directly accesses the mysql database without an abstraction layer, and of course it uses queries that are dependent on a weird, older version of mysql. So there’s no hope of it working, ever.
I’m rather disappointed, but I’ll find another plugin that hopefully does the same thing.
