Various people have written in about their experiences with the Obama campaign in various capacities - attending events, volunteering, being contacted at home, being a precinct captain, etc... - and it does sound like the campaign has made extraordinary use of organizing. People who attend events are contacted, internet tools allow quality organizing and phonebanking from home, etc.
I don't have similar info about the Clinton operation so I can't compare, but if this kind of thing is what ends up making the difference in the primary campaign it'll be truly interesting.
More to say on this when it's over...
