Peter, after listening to the feed for about 30 mins, I came to the same conclusion!
Also, this is also just my opinion and observation, but frankly I don't think a unicom frequency is just that interesting unless you are actually flying towards that airport.
Basically all you hear are a bunch of one-sided pilot calls stating in what leg of the pattern they are located. You also hear a lot of squeals as they all step all over each other and in the quieter unicoms locations, you hear Billy Bob asking Little Johnny where he has been for the last three weeks.
Occasionally you might hear one pilot yelling at another about who cut whom off in the pattern, but those are (hopefully) rare.
TEB, on the other hand, will provide endless entertainment.
You should have heard the controller yell at a VFR aircraft ahead of me one time last year who was cleared to land on one runway, but lined up for the other, cutting me off in the process. That was fun.
