Are fluthers hierarchical?

I was looking at my fluther a few minutes ago and wondering about its organization, when it hit me… this is arranged by lurve, isn’t it? I mean, it’s not alphabetical, and doesn’t seem to be arranged strictly chronologically (which had been my first thought, as most of the new jellies I add end up at the bottom of the fluther). But then I took another look at who’s on top.

So I’m wondering if I got it right: Are all of the fluthers arranged so that the jellies with the most lurve appear first / top?
