Wahlomat was a great starting point for me as someone who is not up-to-date on current party agendas. However, its weakness is that it breaks down answers into yes/no options. For me there were lots of items that required more than that (for example: I was looking for parties who reject the premise of a given question - I would have loved a graphical indicator for those cases). But I have to say, drilling down to get that information was not only possible with the website but was easier than hunting for a given stance on a party's website.

The structural problem (or feature) in Germany is that voting for a party who is not expected to pass 5% in total votes is basically the same as not voting at all. For me as a holder of niche opinions, this is inconvenient. Of course, everybody knows this feature exists to prevent the recurrence of a Weimar Republic-style desaster.

I do wish we (Western-style democracies in general) would make more use of direct democratic measures. Barring that, I would absolutely love to give my mandate to several parties in different areas (for example, give my mandate to the Pirate Party on IP matters, but give it to someone else on social policy).
