It's pie in the sky, but I'm interested in the idea of "immediate delegation representative voting" (that's a phrase I just made up because I don't know if it has a formal name). How it would work would be that you still have your default elected representative for most issues, but on a per-vote basis, a citizen could override the default and designate an alternate representative for that vote, including themselves. So if a citizen felt that a particular person was a better expert on an issue then their representative - they could designate that person to study the bill/policy in depth and cast their vote. One effect here is that if multiple citizens delegate the same people, then those delegates could spend more time studying the issue than an individual voter. Another effect is that we might get representatives for issues (other than our normal political reps) who would collect voting blocks which could bypass the normal political lobby money path. As with many human endeavours, it might turn out to be an even bigger circus, but being able to selectively bypass one default representative has the nice potential of short circuiting the pattern of currying favors with entrenched politicians. The approach is sort of a hybrid of direct representation while still allowing 'expertise' to come into the system.
