I had never heard of that before but it is interesting on a bunch of levels (mechanical, sociological, memetic, etc). My presumption is that you're interested primarily in the idea captured by the this quote by Buckminster Fuller at the bottom of the wikipedia page:

Something hit me very hard once, thinking about what one little man could do. Think of the Queen Mary—the whole ship goes by and then comes the rudder. And there's a tiny thing at the edge of the rudder called a trim tab. It's a miniature rudder. Just moving the little trim tab builds a low pressure that pulls the rudder around. Takes almost no effort at all. So I said that the little individual can be a trim tab. Society thinks it's going right by you, that it's left you altogether. But if you're doing dynamic things mentally, the fact is that you can just put your foot out like that and the whole big ship of state is going to go. So I said, call me Trim Tab.

I'm curious how deep the analogy you're suggesting is. Can you extend it into something more explicit? My naive thought, would be that Eliezer_2007-ish was the trim tab and all of what's happening from ~2009 to ~2013 (Leverage Research included) is more like "the rudder" starting to move, and the ship won't even have visibly changed course until 2020-ish and then only slightly. The place the analogy really seems to fail to me is that it presumes there is this single tiny thing that matters (which is quite complimentary and thus a nice PR angle), when really there are probably thousands of things that will retrospectively be seen to have mattered and the english speaking singularitarian political movement is just one of them.

EDA: I don't understand LW's voting here. Tim was the one with the idea, I just spelled out the implications for the sake of discussion, and his comment's at 1 and mine is 9 now?!? He's the one with the awesome signal/noise ratio and relevant links, not me, but I can't vote myself down to rectify this.
