Can you still consider this blogging?

So I'm going through my feed reader, catching up on this week. I get to Instapundit, and I see that I have 68 posts to read. I scroll down. I swear the words that Glenn Reynolds excerpts out numbers the words he writes two to one. I'm grateful that he takes the time to read a lot because his site is somewhere that I can go to cut through the clutter of sources, but is it still blogging if you add so little content yourself?
