Who is Dave Lull?

If you are a blogger, then perhaps you too have been the recipient of his terse emails informing one of this or that blogworthy tidbit.  Who is this Dave Lull guy anyway?  Patrick Kurp of Anecdotal Evidence provides an answer:

As Pascal said of God (no blasphemy intended) Dave is the circle whose center is everywhere in the blogosphere and whose circumference is nowhere. He is a blogless unmoved mover. He is the lubricant that greases the machinery of half the online universe worth reading. He is copy editor, auxiliary conscience and friend. He is, in short, the OWL – Omnipresent Wisconsin Librarian.
