Do you want to know why they use such a strange voting, instead a normal poll like they used, too?
It is a funny story
In the long run, it is, because the librarians in Germany are a bunch of assholes that never replied to my mails.
So when someone else also did not reply to my mails with some patches, I was so annoyed of not-answering people, that I just put them as fork on a sourceforge project.
A project that a few months ago became a candidate for a project of the month, too, and Sourceforge made a poll on an external voting site.
However, that in turn made someone else really angry, and he started to submit hundred of fake votes.
And that was the last time Sourceforge used a real poll
