Is Blogospheric Energy Episodic?

Is it just me or do other people also find that the number of bookmark-able RSS feeds rises and falls in some episodic rhythm?

There will be weeks where things chug along “normally,” only to be interrupted by an intense burst of blogging energy when several interesting and different ideas appear in just a few days from various bloggers.

It’s not that one interesting idea appears and many people jump on it. Rather, several interesting ideas all appear simultaneously. The blogosphere seems to percolate for a while and then erupt with a volcanic salvo.

One explanation is peaks in my own internal rhythms. Possibly these periods coincide with what I perceive as blogospheric episodes? Some of that must be true. But there seems more to it.

Does anyone else experience this? And, if so, do you have an explanation? It’s kind of spooky to imagine that the blogosphere is somehow organic.
