Liquid Democracy in Loomio

I've been doing some research into various kinds of democracy, and I'm intrigued by the idea of "liquid democracy." This might have already been discussed here, but I wanted to see if anyone else would be interested in this sort of thing.

The basic idea is a democratic system in which most issues are decided (or strongly suggested to representatives) by direct referendum. Considering nobody has enough time and knowledge for every issue, votes can be delegated by topic. Furthermore delegations are transitive and can be revoked at any time. Liquid Democracy is sometimes referred to as Delegated or Proxy Voting. source

So, as I understand it, liquid democracy is somewhere between representative and direct democracy, leaning toward direct democracy. I'm intrigued by this idea of being able to "delegate" the weight of my support on particular issues to particular people. So, if I trust my friend on environmental issues, I can give her my support on those specific issues. This will free me up to focus on the issues and deliberations that I am more knowledgeable about and interested in.

I could see this being a useful addition to the Loomio system for a number of reasons. Personally, I'm not able to keep up with all the different conversations going on at any time, and even if I were able to read them, I wouldn't be able to engage in the background reading needed to really be able to contribute meaningfully. So, either I skim most of the discussions, or I just ignore them.

If, however, I were able to indicate my support for an individual in some way on a specific issue, and that support were made visible to others in the discussions where that issue was being discussed, then at least I would know my support is playing a role in those deliberations even if I wasn't personally engaging in them.

I would imagine this would start very small, a few individuals delegating specific things to close friends. It's a new and odd way of thinking about deliberations. But, eventually, I could see a robust system of liquidity, where support is extended and withdrawn and deliberations are more productive and engaging for everyone.

It would require a system for people to "delegate" their votes, and vote-recording system, so that people can track how their "delegates" vote and make sure they still deserve that support. It would also require some kind of system for people to see how much "support" each person has about specific issues. There would surely be other issues, but these seem like the biggest ones.

But, like I say, I'm only now exploring these theories. Here are some more sources I've been looking at: The Wikipedia article on liquid democracy, Der Spiegel on the German Pirate Party's use of this model, Community Wiki notes on the idea.

So, what do you say? Would this work with the overall goals of Loomio? Could this be implemented in such a way that it takes advantage of both direct deliberative democracy?
