The Slow Way to SPDY — attempting to actually try SPDY for yourself sounds like a nightmare as getting hold of a stable SPDY implementation at this point is not unlike an uphill climb on a slow mudslide – the protocol is currently on its third draft but not really stable, most of the available code is outdated, and despite the links on this page, hardly any of it is easy to get to work in a weekend.

Referendum Tool — New Zealand faces a referendum on voting system (currently “mixed member proportional”), and this page is an interesting approach to helping you figure out which system you should endorse based on your preferences for how a voting system should work (“It is better if the Government is made up of one party, with a majority in Parliament, so that that party can implement its policies, and react decisively to events as they come up” vs “It is better if the Government is made up of a group of parties (a coalition), so that its decisions better reflect what the majority of voters want, even if that means important decisions might be delayed.”). I like this because it helps you understand translate your preferences into a specific vote.
