The rise of RSS readers and aggregators like Memeorandum mean that fewer of us are using our blogrolls or just keeping a log of interesting things we’re finding on the Web; instead, we’re much more apt to write about what everyone else is writing about.
I’m not quite sure I’d agree that RSS and Memeorandum are to blame for this, but there’s not much question that the blogosphere is more herdlike than it used to be. Not a change for the better, I’d say.
