It's pretty simple really.

I have a branching factor > 1.0 which means for every tab I open, upon reading that tab, I find at least one more interesting link, and up another tab comes.

It would converge to infinity if my computer didn't crash in a manner causing chrome to be unable to reload, or I didn't periodically hit chrome bugs in the O(1000)'s tab range.

That is most certainly a part of it as well. Hypertext is a very real thing, even if it's current implementation is not Xanadu fancy.
