I've just voted Stefano Zacchiroli for Debian Project Leader (DPL). The voting period closes tonight, so if you are a Debian developer and haven't yet voted, please do!
Debian uses a Condorcet voting system, which to my non-expert eyes, bears some resemblance to "Single Transferrable Vote" (STV), at least compared to "First Past the Post" (FPTP). There is a debate raging in the UK as to whether Government elections should be counted based on an STV method instead of FPTP, with a referendum on the subject in May.
I'm leaning towards "Yes to AV", but this opinion piece by journalist Stuart Campbell (which argues that people should spoil their ballots) is worth a read.
