Thought begat thought

Henry David Thoreau on keeping a journal:

Perhaps this is the main value of a habit of writing, of keeping a journal,—that so we remember our best hours and stimulate ourselves. My thoughts are my company . . . Having by chance recorded a few disconnected thoughts and then brought them into juxtaposition, they suggest a whole new field in which it was possible to labor and think. Thought begat thought. 

I argue that this, too, applies in blogs.
